Moroso air/oil separator catch can for 1995–1999 BMW M3 applications is a small-body billet aluminum unit finished in black that separates oil and crankcase vapors from intake air to help reduce contamination. Offered as a direct-fit, the black-machined small body combines the same oil-capture functionality with a dark finish to match factory engine-bay styling.
