The K&N 33-2331 high-flow air filter is washable and reusable, made with multiple layers of oil-impregnated cotton. Its four cotton layers capture dust, dirt and contaminants, while its design improves airflow to the engine.
It comes pre-oiled and is designed as a direct replacement for the factory air filter. Under normal highway driving conditions, it should be cleaned every 75,000 km or every 5 years.
