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 62-1360 crankcase vent filter has a K&N embossed chrome-plated steel top with a black rubber base. The 1 inch diameter zinc tube is designed to push in and clamp directly on to metal or plastic tubing where venting is needed. Constructed with a synthetic 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.
