The K&N 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 K&N 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 K&N 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 K&N Xtream Powerlid replacement airbox lid for maximum performance. K&N Xtream Powerlid comes with a K&N air filter element molded into it further maximizing performance. K&N tests their Xtream Powerlid in-house on the Dynojet dynamometer to ensure maximum performance and airflow.
