MMX Performance Billet Washer Fluid Cap – BMW F-Series

MMX Performance Billet Washer Fluid Cap – BMW F-Series

It’s the small details that transform an engine bay. The MMX Performance Billet Washer Fluid Cap replaces the cheap factory plastic cap with a beautifully engineered solid billet aluminium upgrade, finished in gloss black anodising for a clean OEM+ look.

Designed and manufactured in the UK, this is a complete OE replacement, not a cosmetic cover. Each cap arrives pre-sealed to ensure a precise, leak-free fit, delivering a far more satisfying and premium feel than the standard plastic part.

CNC-machined from solid billet aluminium using advanced 5-axis machining, the cap is polished and anodised to maintain its appearance year after year. It’s the perfect finishing touch when paired with other MMX / MMR under-bonnet dress-up components.

Available with MMR or MMX engraved branding, allowing you to tailor the look of your engine bay.
