Crankcase Breather Filte r W/ Chrome Cap - 3/8In

The Vibrant Performance Crankcase Breather Filter with Chrome Cap (3/8 Inch) is an essential component for any engine builder, street racer, or serious enthusiast looking to manage crankcase ventilation properly. As your engine operates, pressure and vapors accumulate in the crankcase—a reality that demands proper venting to prevent gasket blow-out, seal failure, and contamination of your oil.

This breather filter sits at the heart of a clean, efficient crankcase evacuation system, trapping contaminants while allowing trapped gases to escape safely and keeping your engine bay cleaner in the process. Engineered by Vibrant Performance, a trusted name in high-performance intake and ventilation systems, this breather filter features a premium chrome-plated cap that not only delivers a polished appearance but also provides corrosion resistance and durability under engine bay heat.

The 3/8-inch connection accommodates standard crankcase hose sizing and integrates seamlessly into both OEM and custom ventilation setups. The internal filter media effectively separates oil mist from the air stream, preventing that oily residue from coating your intake tract or fouling downstream components—a critical detail for maintaining clean airflow and consistent engine performance over thousands of miles. This component is ideal for carbureted engines, fuel-injected builds, naturally aspirated street cars, and forced-induction platforms where controlling positive crankcase ventilation is crucial.
