Aluminum Breather Cap, Push-In Oval Finned - Polished

• Push-in billet aluminum breather relieves crankcase pressure & blow-by

• Finned oval top with polished finish adds classic hot rod styling

• Fits 1" push-in valve cover breather openings — 4" x 2-3/8" footprint

• Grommet not included — confirm compatible grommet before ordering

This billet aluminum breather cap is designed to help relieve internal crankcase pressure and reduce the risk of oil leaks and blow-by. The push-in design fits a 1" neck size and installs into a compatible valve cover breather opening.

The finned oval top with a polished finish gives it a classic hot rod look, with a 4" x 2-3/8" footprint and 2-3/4" overall height — larger than TSP's round breather caps, so verify clearance around your valve cover before ordering. This cap does not include a grommet; confirm you have a compatible grommet, or that your existing one is in good condition, before installing.
