How often should I clean this filter?

K&N recommends cleaning and re-oiling your filter every 50,000 miles in normal highway driving. Depending on conditions, more frequent cleaning may be required. Use a K&N filter cleaning kit to maintain the filter's performance.

What is the flange made of?

The filter flange is made from pliable rubber. It's designed to create a tight seal, absorb vibration, and allow for some stretch when fitting in-between sizes.

Is this filter legal in California?

No, this universal air filter is not CARB-approved. That means it cannot be used on pollution-controlled vehicles in California.
