Built by Classic Car Studio, the 1955 Chevy Nomad of Art Boze, “GONE-MAD"

Over the past few years, Spectre Performance has featured some pretty sick builds in their SEMA booth and this year is no exception. Rumored to be a bit of a departure from past builds, this 1955 Chevy Nomad is anything but typical. Inspired by a childhood memory turned desire that took more than sixty years to fulfill.

To say Art Boze is just another car enthusiast would be an understatement. This automotive devotee and seasoned car guy out of Swansea, Illinois, has finally built the car of his dreams. As a youngster Art recalls his neighbor had a '55 Chevy Nomad that he routinely ran around town in. Art fell in love with that car and it was right then and there he made a vow to someday own one of those wagons.

He’s had his share of hot rods and muscle cars and of course some noteworthy daily drivers, but none seemed to hold a candle to the Nomad of his neighbor’s from sixty plus years ago. Fast forward to present day and now seemed the perfect time to build the wagon of his dreams.

No stranger to custom builds, he was aware of what it would take to create a very forward-thinking, innovative design. Having worked with Classic Car Studio in the past on other projects, Art placed the call. Classic Car Studio president, Noah Alexander, and the crew were stoked to get on board. Before long they got started on Art’s vision.

First they would need to find a “roller” or at the very least a project car. This task alone could take months or even years. But as luck would have it, Noah found the perfect donor, dusty and neglected in the dry, arid climate of Arizona. It was the "someday" project that never saw someday until Noah came knocking. With Art’s blessing, Noah secured the purchase and the wagon was shipped to the shop in St. Louis, slated for immediate disassembly.

Work started almost immediately after Classic Car Studio took delivery of the Nomad. The body was disassembled and stripped down, the trim pieces removed, then sent out for media blasting. Upon its safe return there really weren’t too many surprises from this sixty year old car. There was poorly repaired body damaged, small rust holes that had eaten away at the floor panels, and a doorjamb repair that would simply need to be replaced. The Nomad needed some serious love but nothing the professionals couldn’t handle.

The next step would be to get the body over to fabrication to begin the overhaul. Old, rusty floors would give way to new, custom fabricated floors. To accommodate a larger, tougher transmission, the fabrication team designed a new tunnel that was added to the new floor. A custom trunk panel was designed and fabricated specifically for this build, as well. While they were at it, mods were made to the floor creating a mini-tub to support chassis modifications plus bigger, wider rubber that would later be added to the rear. The fab team was also responsible for re-creating the wagons doorjamb. Finally, they designed and created a one-off bellypan, adding to the custom look from the ground up. After all the fab work was complete the exterior panels were filled where necessary and smoothed in preparation for custom paint. Close to 2,000 man hours went into the wagons body and sheetmetal work to create the flawless body panels that now show off that green pearl paint!

For a body as big as the ’55 Chevy Nomad you need a chassis that won’t buckle under pressure. Boze and the team at Classic Car Studio selected the sturdy Roadster Shop Revo chassis that comes with 10-gauge fully boxed 4x4-inch framerails. They installed a Flaming River power rack-and-pinion up front with a triangulated four-link rear suspension and Afco coilovers in the rear to provide a comfortable ride. Wilwood Pro spindles, master cylinder, and 13-inch brakes (six-piston front, four-piston rear) give this heavyweight all the stopping power she’ll need.

When it came to deciding what would power the '55, they chose to have an engine built that would be worthy of the teams eye-catching design. The result? An insane big-block created for this diamond in the rough by Shafiroff Racing Engines (SSRE) out of Bohemia, New York. SSRE started with a World/BMP 509ci aluminum block with steel billet caps. They added a Scat 4340 4.250-inch steel crank to the bottom end, plus a Comp “round lobe” billet hydraulic roller cam, along with Comp 1.7 Ultra Pro Magnum roller rockers. Custom 10.75:1 aluminum forged pistons with coated skirts connect to Scat 4340 6.385-inch H-beam steel rods. The motor features SSRE proprietary CNC ported Edelbrock 409 aluminum heads complete with Manley custom stainless 2.25/1.75 valves and Isky “Endure Design” premium roller springs. A pair of Edelbrock Vintage Finish 600-cfm carbs with electric choke are connected by an Edelbrock progressive throttle linkage. Possibly the jewel atop the crown, Classic Car Studio is in process of fabricating a custom intake for the Spectre Performance filter to help this beast breathe. To bring this big-block to life a set of custom 1 7/8” stainless headers feed a 3” exhaust system with Black Widow mufflers adding a throaty tone as they terminate into 3-inch exhaust ports. A Moroso race prepped oil pump keeps the motor cool and lubricated. They’ve added an MSD Ready to Run billet distributor for spark and finally, added a polished aluminum front cover with billet timing pointer, along with a set of GM cast aluminum valve covers, to make this beast of burden beautiful.

This 509ci SSRE built big-block with all the impressive upgrades is rated at 625 hp with 638 pound feet of torque. Backed by the very capable Bowler 4L80E transmission, complete with Bowler Compushift computer, coupled to a Billet 9x11-inch triple-disc lockup stall converter. This setup ties into an ironclad Ford 9-inch rear diff with Pro Iron Case and Truetrac posi. The wagon sports Billet Specialties SLG 15 wheels: 18x8 in the front and 20x12 at the rear all wrapped in Pirelli P Zero tires; 255/40R18 and 335/35R20 respectively.

Looking more like a piece of jewelry than an old wagon, this build evolved in three phases. "First it was going to be a Gypsy Red car with an Indian Ivory top and all the chrome. Next, it changed to a green car with a tan top and the chrome. And finally, after it was all said and done, it was going to be a green car with the gold top and all gold everything,” states Noah. “We have all the renderings lined up still, and the final car is definitely the best. It’s green and gold! You’ve got to be pretty confident in a shop to let them lead you in that direction,” he continued. Custom builds of this caliber take patience and perseverance, from both the builder and the customer. It took over a year for Art to finally come on board with the overall final rendering of the exterior of the wagon. So in the end "Gone-Mad" was dressed in Rescue Green by BASF Glasurit paint and accented with Mercedes Benz Gold Metallic by BASF Glasurit on all the trim.

The interior of the Tri-Five was inspired by old Italian speedboats and cigar lounges

When you go this big on the outside you most assuredly can’t drop the ball on the inside. The interior required thinking outside of the box. Thinking beyond just the interior of a car, Classic Car Studio sought inspiration from some very unlikely places. They created art boards filled with pictures of old Italian speedboats and cigar lounges, bringing to mind a bygone era emphasizing rich masculine tones and amenities. The interior features custom fabricated sheetmetal door panels and console, meticulously covered with the same Relicate leather used on the custom Scat racing seats. The interior trim pieces, dash, and headliner were painstakingly hand painted by a local artist utilizing an airbrush and dry bristle brush technique that mimics the richest of Burl woods. The end result nothing short of amazing. “The devil is in the details,” according to Noah Alexander. “It’s the little things, like the intake, the custom firewall, the interior, all that metal work took probably 800 hours to complete but it makes the biggest impact.”

Classic Car Studio and Art Boze are thrilled to be a part of the Spectre Performance booth at the 2016 SEMA Show. With over 1.5 years into the build, they’d both tell you it didn’t come easy or cheap, but in the end the hard work and dedication paid off in spades. This 1955 Chevrolet Nomad, affectionately nicknamed “Gone-Mad”, is truly a work of Art. It is a statement or rather a testament to making dreams come true. If you will be attending the 2016 SEMA Show, be sure to stop by the Spectre Performance booth, #22755, in Central Hall to see this beautiful creation for yourself.

Spectre-Sponsored Driver, Greg Thurmond Heads to Circuit of the Americas

1965 Chevrolet Corvette at 2015 SEMA show

SCAR debuted to a packed house at the Las Vegas Convention Center during the 2015 SEMA show.

Spectre Performance driver, Greg Thurmond, owner/builder of GTS Customs Corvette Specialists in Southern California, has been building custom Corvettes, similar to SCAR, for close to thirty years. You may recognize him and his 1965 Candy Tangerine Corvette that debuted in 2015 at the Spectre Performance booth at SEMA. He is one of the nation’s premier corvette builders and quite the corvette enthusiast.

Thurmond’s passion for cars came early on, telling us that, “I’ve been a Corvette enthusiast as long as I can remember”. Greg was just three when his dad brought home his first Corvette. Greg’s dad worked as an engineer for Lockheed after serving in the Army. He married his high school sweetheart, began a family, and moved to the suburbs in Southern California and started living the American Dream. For them, that dream included motorcycles, Corvettes and drag boats.

Being raised in Southern California, Greg had a chance to enjoy the great outdoors. Whether it was water skiing, riding bikes or motorcycles, he and his friends spent their days exploring all that California had to offer. Evenings and weekends would find him helping his dad in the garage with their L88 big block, flat bottom drag boat, or tuning up his dirt bike for a weekend at the desert or the track.

Where Thurmond’s passion for cool cars all began. The driveway of his family home in Southern California.

By high school Greg was working at his parents’ upholstery shop where he had developed his skills as a master trimmer and upholsterer. He worked on boats seats, tonneau covers, car interiors, you name it, he upholstered it. He developed skills in body and paint as well. In fact, one of his first paint jobs, at age 15, happened to be his father’s 1963 convertible Corvette that went on to win numerous shows and awards. Following in his father’s footsteps, Greg worked on his own cars, dirt bikes, and ATV’s, doing whatever he could to make them better, make them faster. He learned at an early age that going faster was fun.

He was a natural on a dirt bike and that led him to racing. He garnered the attention of sponsors and magazine editors when competing in Mickey Thompson Stadium races at Pomona Fairgrounds, Ascot Raceway, Indian Dunes, Saddleback, Carlsbad, and Corona. From 1981 - 1987 his dirt career included multiple championships in CRC and AME. With over 50 career wins, he was sought out to test ride for several magazine publications such as 3 and 4 Wheel Action, Dirt Wheels, and Dirt Bike. He test rode for Honda, Suzuki, Kawasaki (dirt and water) and Polaris. In fact, he was even part of Polaris Factory Team for the Baja 1000 in 1986.

Fast forward a couple of decades and we see Greg back out on the track doing what he loves. But this time he has combined his love of cars, specifically Corvettes, with his passion for racing. He started auto crossing in 2012. His chassis builder, Paul Newman of Newman Car Creations, encouraged him to bring his 1964 Corvette out to El Toro for an event called Run to the Coast. With family in tow, he spent a sunshine-filled Sunday trying his hand at avoiding cones. Admittedly Greg was having a blast pushing his show car, Scarlett, to the edge. The months that followed would have Greg modifying his car to behave more appropriately around cones and before long he was a regular, racing at Goodguys events, SCCA races, NMCA competitions and more.

From Spring of 2012 to present, Greg has been adding to his list of performance driving and racing accomplishments. He continues to win his way into Pro Class status at Goodguys and is competing monthly. Whether out at Willow Springs or Pomona Fairgrounds, Autoclub Speedway or Circuit of the Americas, it’s safe to say that Greg is hooked when it comes to going fast and racing.

Last weekend we caught up with him at Optima Search for the Ultimate Street Car (OSUSC) in Austin, Texas, racing at the world class F1 venue, Circuit of the Americas (COTA). Thurmond made the haul from So Cal to Texas in his RV traveling almost 1500 miles to compete at this iconic track. This was one venue that he said is “bucket list” worthy and there was no way he would miss it. Having been a huge F1 fan most of his life, he felt he knew the road course before the green flag even dropped. He told us every turn felt surreal as he had watched the greats like Sebastian Vettel and David Coulthard take the same turns he was taking. To have set foot in the garages where his favorite drivers and their race teams had swapped motors, made improvements, prepped for races, was, “mind blowing”.

Greg began racing with USCA last November at OUSCI. Approached at the Spectre Performance booth at SEMA, Optima Batteries invited Greg to participate at the annual, invite only event that took place at Las Vegas Motor Speedway, where he would compete among some of the nation’s finest amateur racers. Safe to say he loved it as evidenced by his return to OSUSC this year.

As winner of the Participants Choice award at COTA, and receiving 3rd Place for Design & Engineering in the GTL Class, Greg is incredibly proud of what he has been able to accomplish with the build of SCAR. He told us the car was a desert find and with the support of more than 17 different sponsors, whose logos are painted in the stinger stripe on the hood, he would not have been able to be so creative with the build that ultimately is panning out to be an incredible pro-touring ride and crowd favorite.

Greg sits in 22nd position in points for OSUSC after his third event. A mid-season class change has indeed affected his points placement. But he said he’s not worried. He has one more event to make up some much needed points to secure the invite to OUSCI and he is feeling confident. “I feel like I’ve finally got the car dialed in the way I like. The Wilwood brakes are working great and the car is handling like a beast,” he said. The car was barely done a day or two before its debut at SEMA and that didn’t afford him much time for shake down. It’s great to hear that our Spectre Performance driver is feeling confident and decidedly becoming one to watch. He’ll compete again at Autoclub Speedway in Fontana, California, in October, giving him the home court advantage to narrow the gap in the point race. This very well may be the race that gets him back to Vegas for the Optima Ultimate Street Car Invitational - the Super Bowl of Optima Search for the Ultimate Street Car.

Spectre Performance Muscle Car Air Intakes at Auto Enthusiast Day

First generation Mustang at Auto Enthusiast Day

Auto Enthusiast Day in Anaheim, California brought out a handful of muscle cars including this first generation Mustang

When you hear the term air intake, you might think of a bolt-on direct intake that comes in a box with little assembly required. This is true in several cases, but for certain applications, bolt-on specific parts are not available for their custom setup.

Auto Enthusiast Day in Anaheim, California brought out several different types of cars and trucks including imports, off road, and muscle cars. Though there could have been more muscle cars at this year’s event, most of those that did attend were equipped with Spectre Performance custom air intake setups.

Engine bay of LSX-equipped first generation Mustang

The Mustang surprised many with an LSX swap featuring a custom Spectre air intake setup

Often times, these muscle cars are far from their original state, many featuring late-model engines, suspension upgrades, custom body work, and other modifications. These custom modifications make it difficult for manufactures to design make/ model specific bolt-on direct air intakes for these applications. A solution was found when Spectre Performance released their custom air intake component line, allowing people to design their own custom air intake around their specific application.

PCHRODS C10R in Spectre booth in Anaheim, Ca

: The PCHRODS C10R returned for its second year at Auto Enthusiast Day as one of the only pro-touring trucks throughout the entire show

The first car we spotted with a Spectre custom air intake setup was a first gen Mustang. Several people took a quick glance at the Mustang as it looked average on the outside, but for those paying close attention to what laid under the hood, they were in for a shocking surprise. The rise of LS swaps in Mustangs has grown over the past couple years. This Mustang was equipped with an LSX motor, far from the original 289 small block that came with the car from the factory.

There are several benefits when using the Spectre components including proper fitment and the ability for customization. The Mustang did not have tons of room under the hood so a 90-degree angle was needed to clear both the accessory drive and the radiator. The large Spectre cone air filter was used to get as much air as possible into the motor. The filter was positioned away from the motor and radiator (without further extreme modifications) allowing cooler air into the air intake for optimal results.

The C10R was sporting its new 383 storker motor along with a modified Spectre air intake that had to be redesigned to accommodate the throttle body angle

Beside the Mustang sat the infamous PCHRODS C10R, sporting its new 383ci stroker motor. In addition to the motor, the team at PCHRODS upgraded the Holley intake with an MSD Atomic Airforce Intake, forcing them to redesign their Spectre Performance air intake. Though the design was similar, a different angle tube was needed to accommodate the throttle body angle.

1970 Chevy Nova at Auto Enthusiast Day

A 1970 Nova sat in the Currie booth drawing a lot of attention throughout the one-day show with some unique custom modifications

Two red cone filters still sat below the core support in front of the engine. PCHRODS did not want to deviate too far from their original intake design. The original design allowed for the coolest possible air to enter the intake for optimal performance. The tube, which was positioned directly down off the throttle body, sat between the two fans so hot air did not directly blow onto the tube. Though the engine bay of the 1972 C10 is quite large, the trucks modifications restricted the location of the air intake setup if they wanted to keep cooler air temps and overall performance in mind.

Within the Currie Enterprises booth, a 1970 Nova with eye-catching modifications was on display, attracting crowds of people around the car. The Nova, which had a single turbo big block, utilized Spectre Performance air intake components to adapt to their custom application.

A crowd gathered around the Nova to see the single turbo big block under the hood in addition to several Spectre Performance air intake components that were used to adapt to their custom application

The single inlet plenum provided just enough clearance to close the hood while the Spectre Performance air filter fit directly off the turbo. The plenum, which was a four-inch outlet, was reduced to a three-inch setup accommodating the turbo. A Spectre four-to-three-inch reduction coupler was used to adapt the two different sizes. It is common to see a three-inch setup when using a turbo application, but the big block setup allowed for a plenum to be used, which made things a little trickier.

In each of the three vehicles, air intake setups could have been possible without the Spectre Performance air intake components, but having these components made life a lot easier. As we continue to finish out the show season, we will be looking for more Spectre air intake setups to feature on our website. Visit our dealer search tool to find a local dealer that can help you build an intake system for your project or daily driver.

1955 Chevrolet Bel Air Sedan: Half The Price, Twice The Fun

1955 Chevrolet Bel Air before work began

The deception begins as the car is purchased and trailered home surreptitiously

Tony King had been waiting for years to get his hands on a 1955 Chevy Bel Air coupe, just like the one he had driven in high school. According to his son, Tim, his dad was one of those guys who’d walk around a car show, see a 1955, and say “I used to own one of those. I never should have sold it.”

After two heart surgeries and his retirement after 35 years in the construction industry, Tony figured it was time to hook up with his old girlfriend, and started looking for a ’55 Bel Air coupe. Unfortunately, as the Bel Air two-door moved up from enthusiast’s car to collector’s car to iconic All-American status, prices rose accordingly and out of Tony’s budget.

After hour upon hour of scouring Craigslist and eBay Tony spotted a 1955 that met all his criteria: the car was about 90% complete and the current owner had done all the hard work of installing an LS1 small block and a 4L60E automatic. The only downside was the car was a four-door model and not the coupe he’d lusted after for so long. Offsetting his disappointment was the fact that the four door was selling for about half what a two door would. So Tony could both afford to purchase the car and travel around the country with his wife in their motorhome.

1955 Chevrolet Bel Air completed

The completed project, in all its four-door glory

With his father and mother out on an extended road trip, Tim drove the hour from his home to check out the ‘55 and on the way hatched a fiendish plot. He called his dad after viewing the car, which was exactly as advertised, but told Tony instead that the car needed a lot more work than had been indicated, and they should take a pass. Tim bought the car and quietly towed it home, letting only his mother in on the secret. Tim’s plan was to enlist his brother and his best friend to finish the car in 30 days. While it was 90% complete, as the seller stated, anyone who has restored a car knows 10% is still a great deal of work. To complicate matters, work and other commitments pulled Tim away so he had only 12 days to work on the car. Needless to say there were plenty of late nights spent on the car.

One of the several items the car needed was a full wiring harness. In addition, there was no practical way to connect the LS1 to the original gauges. Tim has Dakota Digital gauges in three of his cars, and Tony had always admired them. So of course Tim ordered a VHX gauge set specific to the Chevy’s cluster – which is comprised largely of analog gauges, to fit the theme of the car, somewhat contrary to the company’s name. Another electrical upgrade was an Optima battery, mounted in the trunk. Tim chose Optima because it didn’t require a battery box, plus the LS1 needs more than a few amps to crank it over, and the air bag suspension needs juice to raise or lower ride height. Further plans are afoot to add more electrical components like air conditioning and a stereo to make the Bel Air a true daily driver for Tony. A powerful, reliable battery was key.

One task the previous owner had left Tim was getting air into the engine. Tim called the folks at Spectre Performance and was told “no problem” and asked to call back with a few dimensions. Tim provided Spectre with the information requested and an order was placed. When the box arrived, Tim found everything he’d need to install a high flow conical Spectre Performance air filter in the car, including elbows, tubes, fittings, braces, and adapters for the MAF and IAT sensor were all in the box. According to Tim all he had to do was trim the pipe to the correct length and he had the entire intake system installed in the car in about 15 minutes.

While Tim was thankful for the quality and amount of work done by the previous owner, he came across one odd item. The linkage for the gas pedal wasn’t straight and didn’t travel in the correct arc. A call to Lokar solved the problem, as Tim was able to order a linkage from Lokar that was both straight and swung in the proper arc. Problem solved.

The day had arrived when Tony was to return home. The boys cleaned out the garage and positioned the ’55 front and center. When the motorhome rolled up, Tim hit the button on the garage door opener and the ’55 was revealed. Tony swung around and asked his wife if she’d been complicate in this plan. Then after walking around, climbing in, and crawling under the car for an hour, Tony suggested to Tim they take a ride. Not wanting to break his new toy on the first day, Tony took it easy on the throttle, but Tim admits that the car is fast, faster than he’d expected. So excited was Tony that he kept waking up several times that first night and checking the garage to make certain the car was still there (or perhaps to make certain it wasn’t a dream).

If you go back to the headline, the “Half the Price” reflects the savings in purchasing a four door. “Twice the Fun, on the other hand, refers to Tim’s sheer pleasure in completing and giving this car to his father, and to Tony’s joy in finally owning a ’55 again, which he now drives every day.

Help Your 5.7L Hemi Breathe Clean Air and Make More Power with a Spectre Intake System

Spectre air intake system with blue filter

The Spectre air intake system comes complete with filter, heat shield, and polished aluminum intake coupler, as well as all the necessary hardware for a quick and simple installation.

It's hard to believe but the 5.7-liter Hemi V8 engine has been in production since 2003, which is a longer run than even the first generation of Hemi engines in the 1950s. But then, why change what's not broken? The 5.7-liter "Eagle" engine is based loosely on the all-conquering Hemi race engine of the 1960s. Updates were suggested by some of the same engineers who worked on the second generation "Elephant" Hemi. While not a pure Hemi like it predecessors, the 5.7-liter engine is pretty close. The exact alterations that make it superior to earlier Hemi engines are what provide the performance gains, specifically the squish area within the combustion chamber and the accommodation for two spark plugs. In fact, the combustion chamber somewhat resembles that of the 500 CID "Hemi" top fuel race motor.

Spectre air intake system with blue filter installed in 5.7L Grand Cherokee

There's no doubt you mean business when you lift the hood of your 5.7-liter Hemi Grand Cherokee or Durango with a Spectre intake system installed.

And if there's one thing known about Hemi engines, it's how well they respond to upgrades, particularly ones that feed the engine more air, like the Spectre 9021B intake system.

Designed from the beginning to feature a Multiple Displacement System (MDS), the system shuts down four cylinders of the 5.7-liter Hemi when driving at cruising speeds in order to improve fuel economy and reduce emissions. Both the 2011-2016 Jeep Grand Cherokee and 2011 - 2014 Dodge Durango feature the MDS function.

For Jeep Grand Cherokee and Dodge Durango owners who are seeking both more horsepower and torque from their Hemi MDS, whether using eight cylinders or four, we have a solution. For less than the cost of an upgraded electronic control unit or high performance exhaust system, a Spectre air intake system can increase both in your Hemi-powered SUV.

And while you'll need an expert to recalibrate your engine's ECU if you add a high-performance module, there's no need to do so with an air intake system. Instead, the Spectre 9021B air intake system for Hemi-powered Cherokees and Durangos brings performance increases that can be achieved by a DIY installation that takes around 90 minutes with simple hand tools and with no need to re-calibrate engine electronics.

The Spectre 9021B air intake system moves the air intake away from the hot engine and protects it with a heat shield so only cold, fresh, outside air can reach the air filter. Cooler air is denser, carrying additional oxygen prompting your ECU to add more fuel, increasing horsepower. You've probably noticed the effect when driving your vehicle on a cool morning.

The system utilizes a seven-inch, non-woven, synthetic filter media to help protect your engine from harmful dirt, dust, and debris. The kit comes with the reusable free-flowing air filter, velocity stack, mandrel-bent polished aluminum intake coupler, and a black powder coated heat shield to help prevent hot engine air from entering the intake inlet.

While the Spectre 9021B cold air intake system for Hemi-powered Cherokees and Durangos comes with a blue filter, however Spectre Performance also offers 9021K, which comes with a black filter, and 9021 which comes with a red filter. All three versions offer the same outstanding airflow and filtration capabilities, they're available in different colors to meet customers' preferences.

Spectre air intake systems come complete with all the necessary clamps, screws, and bolts for the look of an OE installation. OEM brackets and hardware are used so that no holes need to be drilled, making for a quick and easy installation. The kit also accommodates all factory emissions and vacuum lines.

The 9021B, 9021K, and 9021 fit the following vehicles:
2016 Jeep Grand Cherokee 5.7L V8
2015 Jeep Grand Cherokee 5.7L V8
2014 Jeep Grand Cherokee 5.7L V8
2014 Dodge Durango 5.7L V8
2013 Jeep Grand Cherokee 5.7L V8
2013 Dodge Durango 5.7L V8
2012 Jeep Grand Cherokee 5.7L V8
2012 Dodge Durango 5.7L V8
2011 Jeep Grand Cherokee 5.7L V8
2011 Dodge Durango 5.7L V8
