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 62-1560 crankcase vent filter has a K&N black rubber top and rubber base. The filter is 1-1/8 inches tall, 1-3/8 inches in outside diameter with a 3/4 inch flange which is designed to clamp directly on to metal or plastic tubing. This air filter is constructed with non-woven synthetic filter media so 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.
