The MMX Performance BMW F-Series Billet Washer Fluid Cap replaces the factory plastic washer cap with a machined billet aluminum one. It is a small detail in a part of the engine bay that most dress-up parts ignore.

The cap is machined from 6061 aerospace-grade aluminum and finished in the MMX signature gloss black anodizing, matching the wider MMX billet under-bonnet range. The MMX logo is engraved into the face.

It is a full replacement for the OE cap rather than a cover that clips over the original, and it arrives pre-sealed for a precise, leak-free connection. Installation is a straight swap, and the factory cap can be refitted at any time.
