K&N Cold Air Intake Kit: Increase Acceleration & Engine Growl, Guaranteed to Increase Horsepower up to 21HP: Compatible 5.7L, V8, 2005-2015 Dodge/Chrysler (Challenger, Charger, Magnum, 300C), 57-1542

The kit replaces your vehicle's restrictive factory air filter and air intake housing. K&N intake systems are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your vehicle's engine to inhale a larger volume of air than the OEM air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. The filters on these kits are washable, reusable and easy to install with tools commonly available.
