K&N intake system for the 02-06 Mini Cooper replaces your vehicle's restrictive factory air filter and air intake housing. K&N intakes are designed to dramatically reduce intake restriction allowing more air flow to your engine. More air means more usable power and acceleration throughout the engine's RPM range. The K&N filter can be cleaned and reused with the K&N filter recharge kit. A vacuum tee will also be required to fit a automatic transmission, which is not included in the kit.
