Description
Upgrade your BMW’s engine bay with the MMX Performance Billet Oil Filler Cap, precision-engineered to replace the OE cap used on S58 and B48E engines. Designed in the UK and CNC-machined from a solid billet of aerospace-grade 6061 aluminium, this cap offers a combination of performance, durability, and aesthetic refinement.
Each cap is manufactured using the latest 5-axis CNC technology, then polished and anodized in MMX’s signature deep gloss black finish for a clean, high-end look that lasts. Unlike decorative covers, this cap is a true OE replacement, engineered to click securely into place with an internally sprung mechanism that ensures a tight, leak-free seal every time.
The MMX Performance cap is pre-assembled with a factory-spec valve and internal spring, so there’s no need to remove or reuse parts from your OEM cap. It’s fully plug-and-play, with a Viton O-ring already installed for optimal sealing and long-term durability.
Designed for both form and function, the cap features a textured grip surface for ease of removal and installation—even with oily hands. It’s part of MMX’s full engine dress-up range, offering a complete aesthetic transformation under the hood.
