Billet Engine Caps & Covers
Billet aluminum caps and covers for the Mustang and GT500 engine bay: oil caps, coolant and intercooler reservoir caps, brake and clutch reservoir caps, fuse box covers, shock tower caps, radiator and supercharger plates. Each one is machined in the U.S.A. from domestic stock and finished to order, so every cap you can see matches the rest of the build. OEM part numbers are listed on each page so you can verify fitment yourself.
Every detail of a well-built engine bay tells a story. The Custom Billet Fuse Box Cover transforms one of the most overlooked areas under the hood into a standout feature — without cutting, drilling, or any permanent modifications to your car.
Now available for two fitments: 1999–2004 and 2010–2014 Mustangs. The billet-style cover installs directly over your existing OEM fuse box cover, retaining full functionality while adding a level of custom detail that sets your engine bay apart. Fiber laser engraved with crisp, permanent detail, it’s a clean, aggressive upgrade that looks right at home alongside your billet caps and other engine-bay accessories.

Your engine bay. Your build. Your name on it.
The factory brake and clutch reservoir caps are an afterthought in plastic. These aren't. Machined from solid billet aluminum and finished in a durable black powder coat, each cap is built to outlast the car — and you decide exactly how it looks before it ships.
Use the builder above to lay out your engraving: choose a Classic Cobra or Modern Cobra (facing your way), SVT, Trinity, Coyote, or Boss 302 — add your own line of text, or leave them blank for a clean machined face. The laser cuts crisp and clean, exposing the raw aluminum beneath the black coating for a sharp, high-contrast finish that won't fade, peel, or wash off.
From $79.99 per cap · $89.99 laser engraved · matched set of two from $145. Have something different in mind? Pick Custom Design in the builder or send your idea to info@dbcousa.com and we'll bring it to life.

Finishing the bay? Our billet shock tower caps cover the strut hardware on 07-14 GT500s.
The engine bay is part of the build too. This Custom Billet Oil Cap is a precision CNC-machined upgrade built on a genuine Motorcraft EC743 OEM cap — delivering factory reliability with a level of detail that turns heads at every show and every hood pop.
Machined from 6061 billet aluminum and finished in a durable satin black powder coat, the cap is built to withstand the heat and demands of daily driving and performance builds alike. Each cap is fiber laser engraved with crisp, permanent detail that adds depth and contrast right where it counts. The billet cover is then professionally press-fitted onto an authentic Motorcraft EC743 clicker-style cap, ensuring proper alignment, sealing, and OEM-level functionality across 3,000+ Ford, Lincoln, and Mercury platform applications.
A small upgrade with a big impact — exactly the kind of detail that separates a good build from a great one.
