Flashark oil catch can is designed to capture excess oil and contaminants that escape past the engine's piston seals and enter the crankcase. While oil is essential for lubrication, some inevitably result in blow-by. The catch can prevent this blow-by from re-entering the engine's air intake, protecting engine performance.

What is the purpose of the baffled oil catch can? Custom grooves in the catch can's inlet increase air turbulence ensuring all the oil sinks to the bottom of the can, leaving nothing but clean air to pass through the 50-micron bronze filter to the intake. An internal baffle keeps the collected oil from splashing around under race conditions.

Are oil catch cans bad for your car? Oil catch cans are simple devices that greatly benefit direct injection engines. The oil catch cans prevent oil and other contaminants from causing a buildup of debris inside the engine's intake manifold
