BMW K&N Performance Air Filters for BMW E9 (1969-1974) 2800CS

Clear BMW chassis
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.
