Flatline Custom Billet Coil Covers

Flatline coil covers bring a clean, smooth-face billet look to the 4.6/5.4 DOHC Mustang engine bay — no ribs, just a flat machined face you make your own. Each pair is CNC-cut from 6061 aluminum and finished in California.

Build yours with the configurator above: pick your body, accent-dot, and lettering colors independently from the 33-color paint-code palette, Black, or raw machined, with optional paint infill. Add your own custom text, upload your own logo, or choose both. Or leave it blank. You can also add your logo laser engraved on the flanks.

Text Style: Slim runs the wordmark full-length across the plate; Normal centers it larger and allows flank engraving. Custom text, a top line, and logo engravings are the same price and go straight to the cart. Custom colors are quoted by email.

Fitment: 1999–2014 Mustang Cobra, 2000 Cobra R, 2003–2004 Cobra, 2003–2004 Mach 1, and 2007–2014 Shelby GT500. Sold as a pair.

Add your Build ID from the configurator to the order notes / Build ID field so we machine the exact build you configured.
