Mishimoto has developed a oil catch can that makes sure you are getting the most out of all your aftermarket performance parts. Over time harmful oil can build up on the turbo, intake manifold, and intercooler piping. The Mishimoto oil catch can will prevent the oil build up from happening. The Mishimoto oil catch can will prevent oil from getting into the pressurized turbo plumbing that can lead to boots blowing off under boost. This can also prevents oil vapors getting into the intake system which can lower combustion temperatures and reduce overall efficiency.
