Good To Know

Q: How often should the air box filter be replaced? A: Inspect it at the start of each season and clean or replace it whenever it looks loaded with dust or debris. Heavy trail use may call for more frequent checks.

Q: Does the foam seal need to be replaced with the filter? A: Replacing the seal at the same time is a good habit since worn foam can let unfiltered air bypass the filter. Confirm the seal seats fully around the air box before closing it up.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
