Product Description

The factory plastic oil fill cap on the Cummins is purely functional, and it's usually the first thing that stands out as an eyesore once the rest of the engine bay starts getting dressed up. The Wehrli WCF100394 replaces it entirely with a CNC machined billet aluminum cap - not a snap-on cover, but a true direct-fit replacement that threads in exactly like the factory part.

The clear anodized finish gives it a clean, premium look that pairs naturally with Wehrli's billet brake reservoir caps for a matched, cohesive engine bay theme. It installs in seconds with no tools, backed by a proper o-ring seal, making it one of the easiest and most affordable ways to add a finished, custom touch under the hood.
