MORE PRODUCT INFORMATION
The MMX Performance billet washer bottle cap for BMW G8x models is a UK-engineered upgrade, crafted from a solid block of aluminium.
Purpose-built to replace the factory plastic cap, it delivers a refined feel and a premium under-bonnet finish that far surpasses the OE part.
Each washer fluid cap is precision-sealed to ensure a perfect, leak-free fit. Unlike simple stick-on covers, this is a full replacement designed to integrate seamlessly. Using the latest CNC 5-axis machining, every cap is meticulously shaped, then hand-polished and gloss-anodised for durability and lasting beauty.
