K&N crankcase vent filters are perfect for racing applications, vintage cars or individuals who want to add some aesthetics to their classic carbureted engine. The 62-1485 crankcase vent filter has a chrome top with a rubber base. The 1-1/4 inch diameter rubber flange is designed to push directly into the valve cover where venting is needed. Constructed with a cotton filter media it can be cleaned and reused repeatedly. A 14.79 milliliter pillow-pack of air filter oil is included. Note: Legal in California only for racing vehicles which may never be used, registered, or licensed for use upon a highway. See knfilters.com for CARB status on each part for a specific vehicle.
