Black Crinkle Push In Air Breather

The Black Crinkle Push In Air Breather by PROFORM is a compact crankcase ventilation solution designed for custom engine builds and modified vehicle applications. This breather serves as a critical component in any high-performance or street rod setup, allowing excess pressure and vapors to escape from the engine block while maintaining a clean, finished appearance under the hood.

Constructed with a black crinkle-finish design, the PROFORM breather resists rust and corrosion while maintaining a professional, factory-quality aesthetic. The push-in fitting design allows for quick, secure installation into compatible valve covers—no threading or fasteners required, just a firm press fit that stays in place. The compact 3.9 x 2.7 x 5.85-inch footprint ensures it fits tight engine bays without interference with spark plug wires, hoses, or other components.

Mechanics and engine builders favor this breather for naturally aspirated applications, as proper crankcase ventilation reduces oil blowby and extends engine longevity. It is compatible with various valve cover designs, making it an excellent choice for small-block Chevy, classic Ford engines, and other custom powerplants.
