How often should I clean and re-oil this filter?

The cleaning interval depends on your driving conditions, but K&N recommends inspecting the filter every 25,000 to 50,000 miles. Clean it more often if you drive in dusty conditions. Use a K&N filter cleaning kit to maintain the filter's performance and warranty.

What is the flange size of this filter?

This filter has a 6-inch flange. The rubber flange is designed to stretch slightly, up to 1/16 of an inch, to accommodate slight variations in intake tube sizes, ensuring a tight and secure fit.

Can this filter be used on a street-driven car?

This filter is a universal fit filter, so it can be used on a street-driven car if it fits properly. However, it is not CARB-approved, so it is not legal for street use in California or other states that have adopted California emissions standards.
