The K&N high-flow air filter is a washable, reusable filter made from four layers of oil-impregnated cotton material. Its design improves airflow and traps dust, dirt and contaminants, while also being engineered to increase horsepower and improve acceleration. 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.
