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 cone-shaped 62-1600BL crankcase vent filter has a K&N embossed chrome top and chrome base. The flange clamps directly onto a 3/8 to 1/2 inch metal or plastic tubing where venting is needed. Constructed with a blue colored synthetic 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.
