The KN Powerlid eliminates restrictive ATV intake snorkels by replacing the stock air box lid with a high-airflow filter lid. The Powerlid works in conjunction with a KN replacement air filter (sold separately) to provide excellent filtration with less restriction allowing increased airflow for more horsepower. The Powerlid snaps in place with no air box modification necessary. All KN Powerlids come with a PreCharger filter wrap for the lid and a carburetor jet selection kit if required. Late model sport and racing ATV machines can get a bigger blast of fresh air with the KN Xtream Powerlid replacement airbox lid for maximum performance. KN Xtream Powerlid comes with a KN air filter element molded into it further maximizing performance. KN tests their Xtream Powerlid in-house on the Dynojet dynamometer to ensure maximum performance and airflow. KN designed the Xtream Powerlid to install easily by simply replacing your stock air box lid. No other modifications are needed. The KN Xtream Powerlid increases horsepower and increases throttle response by flowing more air than stock snorkels. Cleaning the KN Xtream Powerlid is easy because it is constructed with the same oil-impregnated cotton gauze that their air filters are constructed from and can be cleaned up to 25 times with the same KN recharger kit.
