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 62-1390 crankcase vent filter has a K&N embossed chrome-plated steel top with a black rubber base. The filter is 2-1/2 inches tall, 3 inches in outside diameter with a 1-1/4 inch flange which is designed to push on to the existing rubber breather grommets. 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.
