The Last Filter Your Engine Will Ever Need - K&N warranty's their replacement filters for 10 years or 1 million miles. Why would they do such a thing? Because they are engineered to last the life of your engine. K&N uses only the highest quality materials and never compromises. Every 50,000 miles, K&N recommends you clean and re-oil your filter, then put it back in your engine and it will perform virtually like new.

In the K&N tradition of engineering power, the K&N Fuel Injection Performance Kit (FIPK) dramatically reduces intake restriction as it smoothes and straightens 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 torque throughout the engine's RPM range, with even greater power gains in turbocharged and supercharged engines. FIPKs are available for many popular performance vehicles, and are designed to replace the original air filter case without jeopardizing important emission standards.
