Tired of all the keyboard warriors on the internet arguing about what intake makes the most power? So are we, and it’s time to cut through the noise. This article puts three popular intake styles to the test on a 2018 Chevy Silverado: the new K&N NextGen, a closed box competitor, and a discount open airbox competitor. Using airflow, dyno, and track tests, we measure real-world performance to find out what intake is best!
See how K&N gives you the most Horsepower on a stock tune with proven dyno results to give your vehicle power you can hear and feel. Upgrade to a K&N Cold Air Intake or K&N Air Filter for enhanced vehicle performance, cost savings, and superior engine protection with easy maintenance and long-lasting durability. Experience the benefits of improved airflow and protection, backed by a lifetime limited warranty.
For over fifty years, K&N® has been a pioneer in the field of automotive filtration engineering. Now, those five decades of expertise have been applied to an exciting innovation for your home—K&N’s brand-new lifetime washable home air filters.
Help protect the engine of your Silverado or Sierra and gain a guaranteed increase in horsepower and torque with the K&N® 63-3109 air intake system, engineered specifically for 2019 Chevrolet Silverado and GMC Sierra 1500/2500 5.3L/6.2L V8 models. The K&N® 63-3109 roto-molded air box intake system boasts an estimated power increase of 15.7-horsepower and 32.5 lb./ft. of torque*, and up to 25% more airflow than the factory intake system.
Designed for 3.5L V6-powered Ford F150 pickups the Spectre air intake system adds power and response
The sturdy and proven Duratec 35 3.5L V6 engine was available in 2015 – 2017 Ford F150 models. The Duratec 35 featured a sophisticated design that included double overhead camshafts operating four valves per cylinder heads through direct acting mechanical bucket camshaft tappets. The camshaft were components of the twin-independent variable cam timing (Ti-VCT) system that increased power while improving fuel economy.
Although named Duratech in advertising distributed to the public, it was a clean sheet of paper design internally designated as the Cyclone; it had nothing in common with earlier generations of Duratech engines. The Duratech 35 developed 282 horsepower and 253 lb-ft of torque. Not surprising it was selected by the automotive industry magazine Wards Auto for its 10 Best Engines list.
Introduced in the 13th generation of F150, the Duratech 35 was positioned as the base engine. Above it in the line were the 325 horsepower 2.7L EcoBoost twin-turbo V6 and the 385 horsepower 5.0L V8. For 2018 the 3.5L V6 was replaced by a 3.3L V6 that actually produces more power than the 3.5 – an increase of eight horsepower.
The Spectre HPR air filter utilizes a non-woven synthetic filter media
If you own a 2015-2017 Ford F150 powered by the 3.5L V6 Duratech, consider installing a Spectre 9048 air intake system to make up some of the difference between your truck and more powerful Ford F150 models.
The Spectre 9048 adds performance and response by feeding your Duratech 35 cooler, fresh air than the stock system can provide. Fresh outside air is now fed to an oversized seven-inch tall HPR9892 tapered conical air filter protected within a two-piece heat shield that installs into the space of the factory air box. The HPR9892 is a low-restriction air filter, constructed of a non-woven synthetic filter media.
Once filtered, intake air is directed through a velocity stack into an aerodynamically-verified polished aluminum intake tube that accommodates the factory mass air meter, IAT sensor, and other required hoses. Installation is a straightforward process that can be accomplished in a few hours or less and requires only a few common hand tools and no drilling.
And once you’ve installed your Spectre 9048 air intake system you’ve eliminated the need to buy another air filter for the life of your covered 2015 – 2017 Ford F150 powered by the Duratec 35 3.5 L V6 engine. The only maintenance required is a simple service you can do all by yourself. That’s because the Spectre HPR9892 air filter element is washable and reusable.
The Spectre 9048 is designed to fit the following vehicles:
2017 FORD F150 3.5L V6 Fuel Injection - Exc. Turbo 2016 FORD F150 3.5L V6 Fuel Injection - Exc. Turbo 2015 FORD F150 3.5L V6 Fuel Injection - Exc. Turbo
