Product Details

Features

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

Description

This billet aluminum breather cap is designed to help relieve internal crankcase pressure, reduce blow-by, and support cleaner engine operation. The push-in design fits a 1" neck size and installs into a compatible valve cover breather or PCV opening, with a grommet included for the install.

The round, plain top with a polished finish gives it a clean, smooth appearance in the engine bay — a straightforward upgrade for maintenance, restoration, or custom valve cover setups. Before ordering, confirm your valve cover's opening style, neck diameter, and grommet size match this cap's 1" push-in fitment.


Applications
