This is absolutely the least expensive and easiest way to improve horsepower and extend the life of your air filter! The sandwiched layers of cotton gauze, specially treated with K&N air filter oil, provides five times more filtering surface over the element circumference. This serves to smooth incoming air flow while reducing intake restriction and thereby boosting horsepower. K&N Performance Air Filters come pre-oiled for easy installation and with K&N's famous 1,000,000 mile warranty. K&N filters are easy to clean: wash with cold water every year and re-oil it every two years for a lifetime of performance.
