The K&N 33-2766 air filter is a washable, high-flow air filter for the Mercedes-Benz V-Class W638. It is made from four layers of oil-impregnated cotton material, which help improve airflow while capturing dust, dirt, and contaminants.
The filter is reusable, pre-oiled, and designed as a direct replacement for the factory air filter. Under normal highway driving conditions, it needs to be cleaned every 75,000 km or every 5 years.
