GrimmSpeed Version 2 Bolt Oil Cap (Gold) – Subaru Universal

The Engine Bay Detail That Costs Almost Nothing and Looks Like It Did

The GrimmSpeed Version 2 Bolt Oil Cap in Gold is a billet aluminum replacement for the factory plastic oil cap on Subaru EJ and FA-series engines. Knurled grip ring for positive hand-tightening, machined GrimmSpeed logo on top, and a finish that won’t crack, fade, or look tired the way factory plastic does after a few years in the engine bay heat. Universal Subaru fitment — threads directly onto the factory valve cover location.

Billet Aluminum — The Correct Replacement for Factory Plastic

The factory Subaru oil cap is plastic — functional but prone to cracking and fading over time in the engine bay environment. The GrimmSpeed Version 2 Bolt Oil Cap is machined from billet aluminum with a knurled grip ring that provides positive grip for hand-tightening without tools. The design prevents over-tightening that can damage the valve cover threads, and the oil-resistant finish maintains its appearance indefinitely unlike factory plastic.

Universal Subaru Fitment — Thread-On at the Factory Location

The GrimmSpeed oil cap threads directly onto the factory valve cover oil cap location on all Subaru EJ and FA-series engines — the same thread pitch and sealing surface as the factory cap. No adapter, no modification. The GrimmSpeed logo is machined into the top of the cap for an intentional engine bay appearance.

Straight From Subispeed

The GrimmSpeed oil cap is the first thing people notice when they open the hood on a clean Subaru build — it’s a small detail but it’s right at eye level and the factory plastic cap looks out of place alongside upgraded hardware. The Gold finish suits a wide range of engine bay color schemes and the knurled grip makes oil changes slightly less annoying. Low cost, zero installation complexity, permanent fix for a small but persistent eyesore.

Every GrimmSpeed product is engineered, tested, and refined in-house, and their focus on Subaru means the fitment and function reflect a deep understanding of the specific platforms they cover.
