Description
MMX BMW F-Series Billet Washer Fluid Filler Cap – MMR Logo replaces the standard plastic cap with a machined under-bonnet detail that is sturdier, cleaner and easier to grip.
The cap is CNC-machined from 6061 aluminium, finished in gloss-black anodising and supplied as a complete replacement rather than a cover. A pre-installed seal helps retain the factory-style fit.
