Get More Power From Your 5.7L Hemi with a Spectre Cold Air Intake System

Chrysler 300C with Spectre Air Intake

When Mercedes bought the beleaguered Chrysler Corp. in 1998, they set about reinventing its image. To do that, German and American engineers collaborated to develop the rear-wheel drive LX-platform, then they developed an all-new 5.7L Hemi V8 to power the top models. With a versatile RWD chassis and modern Hemi engine to work with, Daimler-Chrysler designers went to the archives and recreated three of the brand's most iconic models. Now under Fiat control, these second generation Hemi Mopars continue to set the standards for American performance and style. The 2011-2015 Chrysler 300C & 2012-2015 Chrysler 300S remain the brand's flagship sedans, and harken back to when 'Chrysler 300 Letter Cars' were the preferred banker's hot rod. The 2011-2015 Dodge Charger R/T 5.7 Hemi gained two doors, along with the respect of muscle car fans, and police departments. And just like its namesake did decades ago, the 2011-2015 Dodge Challenger 5.7 Hemi became the automaker's main competitor in the modern muscle car wars. But just because you own one of these rumbling monsters, doesn't mean you have to settle for 368-375-hp. Especially when a Spectre Cold Air Intake System can unlock more of your Hemi's true horsepower capability.

A Hemi engine gets its name from the hemispherical heads that allow it to create so much horsepower. Unlike the more common angular head design, the heads on a Chysler/Dodge 5.7L Hemi are concave, with oversized intake valves, and spark plugs that sit at the very top of the combustion chamber. This additional space allows the dome-shaped pistons to create a more highly pressurized fuel/air mixture as it travels upward. When the spark plugs ignite this volatile mix, the extra pressure causes a more powerful explosion, and the hemispherical shape contains the heat, so the gas is consumed more completely. The force that's generated during this Hemi-optimized combustion cycle (i.e. Horsepower), forces the piston back down, turning the crankshaft, and ultimately the rear-wheels. One way to increase the horsepower and torque of your Chrysler 300C Hemi, Dodge Charger Hemi, or Dodge Challenger Hemi, is simply to inject colder air into the cylinders. The additional oxygen molecules in cold air will cause the gas to detonate more forcefully, and that creates more wheel-turning horsepower. Fortunately, the Spectre 9036 Cold Air Intake makes all of that science as easy as turning the key and hitting the gas.

On an OEM HEMI 5.7 liter intake system, air gets sucked through a small opening in the bottom of the airbox, before being forced through a thick paper air filter. As the miles rack up, dirt starts to collect on the surface of the OEM air filter, which reduces the amount of air that can pass through it. Once the air gets past the filter, it's hurled down a narrow plastic intake tube that's full of uneven, accordion-like surfaces. This causes the air to bounce around and become turbulent, which increases the temperature, and reduces its oxygen content. The Spectre 9036 Cold Air Intake System ditches those stock, power-killing components and increases horsepower by delivering a higher volume of smooth, oxygen rich air to the cylinders.

To add horsepower to your 5.7L Hemi, the Spectre 9036 Air Intake System replaces the factory airbox with a large synthetic Spectre performance air filter, which is protected from hot engine air by a powder coated steel heat shield that seals against the hood. This reusable high-flow filter can feed more air into the system, and the oiled synthetic material is able to trap more contaminants than a conventional paper filter. Once the air is cleaned, it gets funneled to the engine through a wide diameter polished aluminum intake tube. The smooth interior surface and wide angle bends virtually eliminate air turbulence, and creates an unobstructed airflow path to the cylinders.

Thanks to the cold air supplied by the Spectre 9036 Air Intake, your 5.7L Hemi will be able to make more horsepower and torque. Plus, you won't have to make any under-hood modifications, or reprogram the ECU. Using just a few simple tools, you can remove the factory intake and install your new Spectre cold air system. This should only take about 90 minutes. And to make things easier, there's even an integrated fitting for the stock temperature sensor.
