Description
Upgrade the small detail everyone sees when the hood is up. The MMX billet washer fluid filler cap replaces the flimsy factory plastic cap with a precision CNC-machined 6061-T6 aluminum piece, black anodized for a durable, OEM-plus finish. Designed and engineered in the UK, this is a full OE replacement (not a stick-on cover) that delivers a refined look and premium feel.
Built on modern 5-axis machining, each cap is shaped to tight tolerances, hand finished, and pre-sealed for a leak-free fit. It’s the perfect finishing touch to the MMX range of billet caps.
