How often should I clean and re-oil my K&N filter?

K&N recommends cleaning and re-oiling your filter every 50,000 miles for normal highway use. If you drive in dusty conditions, you may need to service it more often. Use a K&N filter cleaning kit to maintain the filter's performance and warranty.

What size is the filter?

This filter has a 3-7/8 inch flange, 7-1/2 inch base, 5 inch top, and 7 inch height. Because it's a universal fit, measure your existing filter or intake to ensure this K&N filter will fit your application.

Is this filter street legal?

This filter is not CARB-approved, so it is not legal for street use in California or other states adopting CARB emissions standards. Check your local regulations before installing.
