Product Description

The K&N HA-4504 is an off-road replacement air filter built specifically for the 2004-2005 Honda TRX450R, designed to handle extended use in dirty, dusty riding conditions while still providing clean carburetion even at high altitude -- generally without requiring any jet changes. Pleated cotton media, layered across multiple sheets of woven gauze, delivers a large filtration area with low restriction, giving the engine more airflow for increased horsepower and acceleration over a stock filter.

It fits directly into the factory air box with an application-specific sealing bead for a precise, reliable seal, and like all K&N filters, it's washable and reusable rather than a one-time-use disposable part. For riders running in heavier water or mud exposure, K&N's Drycharger wrap (HA-4504-TDK) is available separately to add extra water resistance, and the Powerlid airbox cover (HA-4504-T) is also available separately to further open up airflow.

This is an off-road specific filter, not intended for regular on-road driving conditions -- improper installation will void the warranty.
