The K&N 62-1380 crankcase vent filter clamps onto 1-1/4 inch vent tubes or outlets on racing setups, vintage cars, and classic carbureted engines.

  • Washable Cotton Filter Media: Four-layer progressive cotton gauze traps contaminants effectively and cleans with soap, water, and re-oiling for repeated use
