Green Cotton Air Filter induction kits are derived from their involvement with developing motorsport air filters. The purpose of the Green induction kits is to deliver maximum amounts of unrestricted, high volume, air straight to the engine. The higher the air flow the greater the engine efficiency, horsepower, throttle response and torque throughout the engines rpm range. Fitting a Green Cotton Air Filter will not affect the emissions standards of your vehicle. Installation is straightforward, with minimum technical knowhow and a few common hand tools needed.
