Moroso 85458 Push-In Valve Cover Breather with PCV Valve

The Moroso 85458 is a one-piece push-in valve cover breather featuring an advanced fiber foam design that helps maintain a cleaner engine bay. This breather is engineered to trap oil mist and drain it back into the valve cover rather than allowing it to escape through the air vents, reducing oil consumption and keeping your engine compartment clean.

Key Features:

• One-piece push-in design for easy installation without clips or fasteners
• Fiber foam element traps oil and drains it back into the valve cover
• Fits valve covers with 1.22-inch diameter holes
• Includes integrated PCV valve for crankcase ventilation
• Universal fit for Moroso valve covers and other brands with compatible hole size
• Helps reduce oil vapor emissions and maintains cleaner engine operation

This breather is ideal for performance and racing applications where effective crankcase ventilation is essential. The fiber foam material provides excellent filtration while the drainage design prevents oil from being expelled onto engine components or the ground.
