The Finned Aluminum Oval Push-In Breather – Polished adds a distinct, finned oval shape to the engine bay with a polished finish. Billet aluminum construction with a finned top style sets it apart from round breather designs, giving the valve cover a sculpted, dress-up 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, and Chrysler V8 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.
