MMX Performance Billet Fuel Cap

The MMX Performance Billet Fuel Cap is a precision-engineered upgrade designed to enhance one of the most frequently used touchpoints on your vehicle. Machined from a solid block of 6061 aerospace-grade aluminum, this cap replaces the factory plastic unit with a premium, durable solution that delivers a 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 CNC-machined using advanced 5-axis technology, then hand-finished to ensure a precise fit and long-lasting surface that resists fading, wear, and corrosion over time.

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 ensure proper fuel tank pressure and ease of use. The cap securely fits into the factory holder during refueling and closes with a satisfying engineered click, reinforcing its premium construction.

A simple yet rewarding upgrade, the MMX Performance Billet Fuel Cap adds a level of quality and attention to detail that is experienced every time the fuel door is opened.
