| | The Last Air Filter Your Engine Will Ever Need - K&N warranty 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 use only the highest quality materials and never compromise. Every 50,000 miles, K&N recommend you clean and re-oil the filter, then put it back in your engine and it will perform virtually like new.   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 manufactures three high performance kits for the automotive applications.
