Moroso 25901 Valve Cover Breather Kit Filtered Push-In

The Moroso 25901 is a filtered valve cover breather kit designed for high-performance and racing engines. Moroso's valve cover breathers allow crankcase gases to vent safely while keeping dirt, dust, and airborne debris out of the engine, helping maintain a cleaner engine environment and extending engine life.

Key Features:

• Filtered breather design traps contaminants and prevents debris from entering the engine
• Push-in style installation for Moroso valve covers with standard punched holes
• Available in half-hooded and non-hooded styles for maximum airflow flexibility
• Cleanable and reusable filter media — simply clean and re-oil before reinstallation
• Chrome finish for a polished, show-quality appearance
• Includes valve cover grommets for secure, rattle-free fitment
• Designed to drain trapped oil back into the valve cover rather than allowing it to escape through the air vents

Moroso's valve cover breathers are a trusted solution in the performance and racing community, providing reliable crankcase ventilation without sacrificing engine protection. The Moroso 25901 breather kit is a straightforward upgrade for any performance build using Moroso valve covers.
