The COBB Tuning Subaru Oil Cap brings a bit of class to your engine bay. Available in a black anodized finish, this billet oil cap will keep oil in your engine with a bit of style. Knurling around the sides of the oil cap makes it easy to grip when loosening tightening. The stock plastic oil cap gets brittle and discolored over time, but our anodized pieces will keep their color and their style for years to come!
