Product Details

Features

Description

The Polished Aluminum Ball Milled Round Push-In Breather adds a machined, show-quality finish to the engine bay while supporting crankcase ventilation. Billet aluminum construction with a polished finish and ball-milled top style gives the valve cover area a custom-built appearance.

This breather is sized to a 1" neck and pushes into compatible valve cover ventilation openings — neck or inlet sizing must match the valve cover grommet, hose, or opening style for proper fitment. It's commonly used on universal hot rod, muscle car, truck, and performance builds, including Chevrolet, Ford, Mopar, and GM engine applications with matching valve cover openings.

Before installation, verify neck diameter, grommet size, PCV routing, and valve cover opening style, along with clearance around the rocker cover, coil, and hood.


Applications
Fits compatible push-in valve cover ventilation openings sized to a 1" neck. Commonly used on universal hot rod, muscle car, and truck builds, including Chevrolet, Ford, Mopar, and GM engines with matching valve cover openings.

Construction & Finish
Billet aluminum body with a polished finish and ball-milled top style — diameter and height are both 2 1/2". No grommet included, so the valve cover opening must accept the push-in neck directly.
