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 62-1515 crankcase vent filter has a K&N embossed chrome top, rubber base and comes with a deflector shield to protect against engine heat. The 1-3/4 inch inside diameter rubber flange is designed to clamp directly onto metal or plastic tubing where venting is needed. Constructed with a cotton filter media it can be cleaned and reused repeatedly. 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.
