K&N crankcase ventilation filters are perfect for racing applications, classic cars, or for those looking to add some aesthetics to their classic carburetor engine. The 62-1330 crankcase ventilation filter features a K&N stamped chrome-plated steel top with a black rubber base. The 1.3 cm diameter zinc tube is designed to push in and clamp directly onto metal or plastic tubing where ventilation is needed. Made of a synthetic filter material, it can be cleaned and reused repeatedly.
