In the K&N tradition of engineering power, K&N Performance Kits 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, with even greater power gains in turbocharged and supercharged engines. The filters on these kits are washable and reusable.
K&N's Fuel Injection Performance Kits (FIPK) are K&N's ultimate performance product. These kits are street legal in all 50 states and are designed to increase horsepower as much as 10%! All FIPK kits come with a 10 year / million mile limited warranty and come complete with a recharger filter care service kit.
K&N Aircharger Performance Kits are similar to the FIPK's, but they do not have all of the necessary emissions fittings to make them street legal in all 50 states. These kits are designed for horsepower gains of as much as 10%, and are designed for off-road and racing use.
