Question about this product?

We're happy to help.

The MMX Performance Billet Fuel Cap is a precision-engineered upgrade designed to enhance one of the most frequently used touchpoints on your vehicle. CNC-machined from a solid block of 6061 aerospace-grade aluminum, this cap replaces the factory plastic unit with a premium, durable alternative that delivers a more refined feel every time you refuel.

Finished in a gloss Midnight Black anodized coating and laser-etched with the MMX logo, the cap provides a clean OEM+ appearance that complements both factory and modified vehicles. Each unit is produced using advanced 5-axis CNC machining and hand-finished to ensure precise fitment and a durable surface that resists fading, corrosion, and everyday wear.

Beyond aesthetics, the MMX Billet Fuel Cap retains full OEM functionality. It features a new rubber O-ring seal, integrated pressure relief valve, and locating tether to maintain proper fuel tank pressure and factory-style usability. The cap also fits securely into the factory fuel door holder during refueling and closes with a precise engineered click.

Compatible with all BMW models produced from 1997 onward, as well as modern MINI models and the Toyota GR Supra A90 / A91, the MMX Performance Billet Fuel Cap offers a simple way to add premium materials and engineering to an otherwise overlooked factory component.
