Experience Uninterrupted Performance with the Hybrid Racing K-Series Crankcase Breather Filter

Revitalize your Honda K-series engine's efficiency and longevity with the precision-made K-Series Crankcase Breather Filter. Tailored for K20/K24 engines, this essential component replaces your stock valve cover breather port fitting, empowering your OEM PCV system to work optimally by allowing only clean, filtered air into the crankcase.

Key Advantages:

• Seamless Fit: Specifically designed for Honda K-series (16–19mm inlet), offering a direct replacement without hassle.
• Resilient & Reliable: High-flow, washable filter media ensures long-term protection from dust and debris.
• Built to Last: Robust, oil-resistant materials and secure clamp-on mounting guarantee a durable performance.
• Optimized Airflow: Promotes clean airflow to maintain balanced crankcase pressure and improve engine reliability.
• Versatile Utility: Perfect for naturally aspirated and mildly modified engines seeking combustion efficiency and clean ventilation.

Understanding its Mechanism:

What happens during engine operation? A small degree of combustion blow-by is inevitable, escaping past piston rings into the crankcase. The PCV system, a marvel of engineering, allows for this pressure to be reclaimed through the PCV valve into the intake manifold, ensuring a stable, efficient engine environment.

The Hybrid Racing crankcase breather filter, placed strategically over the valve cover port, introduces pristine air back into the crankcase. It acts as a guardian, ensuring contaminant-free airflow and supporting the engine's internal health and performance.

Critical Note for Enhanced Engines:

If your set-up includes turbocharging, supercharging, or features high compression, it’s essential to manage elevated crankcase pressures. In such cases, this breather filter isn’t apt as a vent outlet due to potential pressure buildup. Instead, we advise installing an oil catch can system for optimal pressure and oil vapor management.
