How do I clean this filter?

Use K&N's air filter cleaner and oil kit. The cleaner removes dirt and grime, and the oil restores the filter's ability to trap contaminants. Clean and re-oil every 30,000 to 50,000 miles, depending on driving conditions.

The flange is 2.5 inches inner diameter, and can stretch slightly. This allows the filter to fit snugly on a variety of intake pipes.
