K&N 1in Flange ID x 2in OD x 1.5in H Rubber Base Crankcase Vent Filter 62-1370 Universal Fit

The K&N 62-1370 crankcase vent filter directs filtered air into the intake for racing applications, vintage cars, and classic carbureted engines. This universal breather with 1 inch clamp-on flange pushes into and clamps onto 1 inch ID metal or plastic tubing for secure venting. Its synthetic media filters contaminants while allowing high airflow, and the design supports repeated cleaning for long-term use.

  • Chrome-Plated Steel Top: Embossed K&N logo on durable chrome finish adds style to engine bays while resisting corrosion
  • Black Rubber Base: 2 in (51 mm) outside diameter base with 1.5 in (38 mm) height provides stable mounting and vibration dampening in engine compartments
  • Synthetic Filter Media: Captures fine particles from crankcase vapors while maintaining airflow, washable with K&N cleaner for reuse
  • Compact Design: Low-profile 1.5 inch height fits tight spaces on valve covers, PCV locations, or breathers without interference
