How often should I clean this filter?

Cleaning depends on your driving conditions. Inspect the filter regularly, and clean it when you see a buildup of dirt and grime. A dirty filter restricts airflow and reduces performance.

What kind of oil should I use to re-oil the filter after cleaning?

The filter includes a 14.79 milliliter pillow-pack of air filter oil. After cleaning, apply K&N air filter oil evenly to the cotton gauze to maintain its filtration properties. Do not use excessive amounts of oil.

Is this filter legal for street use?

This filter is not CARB-approved, so it is not legal for street use in California. Check your local regulations regarding crankcase vent filters.
