Universal Racing Aluminum Alloy Oil Catch Can Oil Tank Breather Tank, Capacity: 300ML (Black)

1. An oil catch can is used in turbo applications, or high-performance racing applications where excessive blow-by (leakage past the piston rings) of air and fuel vapor occurs. This creates a positive pressure in the crankcase. During engine operation, blow-by gases, as well as oil mist from the rotating components of the engine, pass through the PCV valve and are routed back into the intake for the engine to burn off. However, some of the oil mist and other by-products settle along the engine intake and over time form a gunk. The oil catch tank collects such oil mist and condenses the fuel vapors while allowing cleaner gases to be passed back into the intake. 2. All oil vapor expelled by your turbo charged motor before it can harm your cars performance keeps the engine clean even under hard driving conditions. 3. The catch can will keep out the Dirt and oil get inside Your Engine from your intake system Increases horsepower and Prolongs your engine life. 4. Material: aluminum alloy 5. Capacity: 300ML
