Description

Finned Aluminum Oval Push-In Breather Black for Crankcase Ventilation and Engine Dress-Up

This oval billet aluminum breather is built for compatible valve cover ventilation openings and crankcase ventilation systems. The black finish gives the engine bay a clean dress-up look, while the finned design supports proper airflow for crankcase ventilation.

The 1" neck or inlet sizing must match the valve cover grommet, hose, or opening style for proper fitment. Use it for hot rod, muscle car, truck, and performance applications where crankcase pressure control and appearance matter.

Verify neck size, PCV routing, hose barb size, grommet compatibility, and valve cover opening before installation.
