Moroso air/oil separator catch can for 2007–2011 Jeep JK 3.8L applications is a small-body billet aluminum unit with a black finish that separates oil and crankcase vapors from intake air to help reduce contamination. Offered as a direct-fit solution for those JK models, the black-machined small body offers the same targeted oil-capture function while matching darker engine-bay trim.
