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

The cleaning intervals depend on your driving conditions. K&N recommends inspecting your filter every 30,000 to 50,000 miles and cleaning it when you see a buildup of dirt and debris. Off-road conditions will require more frequent cleaning.

What is the flange size of this filter?

This filter has a 2.75 inch (2-3/4in) flange. The pliable rubber can stretch slightly to fit in-between sizes. Always measure your intake before ordering to ensure proper fitment.

Is this filter legal for use in California?

No, this filter is not CARB-approved. That means it is not legal for use on pollution-controlled vehicles in California. Check your local regulations before installing.
