Replace That Plastic Cap With Something That Deserves The Spotlight

If you’ve spent time dialing in your Cummins build, the last thing you want is a cheap plastic oil cap standing out like a sore thumb. The Wehrli 100395 Billet Oil Fill Cap in black anodized finish is the sleek, durable upgrade that brings your engine bay one step closer to show-ready. It’s not just a cosmetic cover, it’s a full billet replacement that ditches the flimsy factory piece and locks in with a secure, o-ring sealed fit. The black anodized finish gives off that stealthy, premium look that pairs perfectly with any high-end under-hood setup. It installs in seconds and looks right at home next to other Wehrli components, especially if you already have their billet brake reservoir cap. Even the Wehrli Custom logo engraved on the bottom gives it that extra touch of craftsmanship that enthusiasts appreciate. Whether you're showing off at meets or just want the satisfaction of a fully dialed-in engine bay, this is one of those small upgrades that makes a big impression every time you pop the hood.

Precision Machined Cap Designed For Long Term Durability

The Wehrli 100395 Billet Oil Fill Cap is a CNC machined aluminum component built for Dodge RAM 2500 and 3500 trucks with Cummins 5.9L and 6.7L engines from 1998.5 through 2024. This is a complete replacement cap, not a slip-on cover, ensuring an OEM-grade fit and improved longevity compared to stock plastic caps. It features a durable black anodized coating for corrosion resistance and an integrated o-ring seal for proper sealing and pressure retention. The cap is machined to tight tolerances in the USA and designed to be a direct drop-in part, requiring no tools or modifications to install. Its fitment is compatible with most factory valve covers but is not designed for use with WCFab X D&J billet valve covers, specifically models WCF100330 and WCF100366. An engraved Wehrli Custom logo on the underside adds a subtle design touch, while the clean finish elevates the overall look of the engine bay. This part is ideal for those seeking a functional, aesthetically refined upgrade that performs just as well as it looks.
