Specs & Features

• Available in Medical-Grade Black Delrin for heat resistance or CNC Machined 6061 Aluminum for superior strength and style.

Product Description

Let’s be honest: the stock plastic oil cap on your car is an afterthought. Over time, it gets brittle, discolors from heat, and ruins the look of an otherwise clean engine bay. COBB Tuning gives you two distinct ways to solve this, depending on how you use your car.

Option 1: The Track Day Hero (Delrin) Have you ever tried to add oil after a hot lap, only to play "hot potato" with a scorching metal cap? Metal retains heat; Delrin doesn't. COBB’s Delrin Oil Cap is made from a medical-grade polymer that stays cool to the touch even when the engine is blazing hot. It saves your fingertips (and your phone's fingerprint scanner) from getting burned. Plus, with the included shim kit, you can ensure the logo is always perfectly horizontal when tightened—satisfying that need for symmetry.

Option 2: The Billet Classic (Aluminum) If you prefer the solid, mechanical feel of metal, the Aluminum Oil Cap is pure engine jewelry. Precision machined from 6061-T6 Billet, it features aggressive knurling that looks tough and offers incredible grip. Unlike the stock plastic that eventually cracks, this anodized piece will look brand new for the life of the car. It’s the small details that separate a "build" from a "daily driver." Treat your engine to the fit, finish, and functionality of COBB.
