MMX Washer Fluid Filler Cap — BMW G-Series (MMX Logo)
Upgrade your BMW G-Series engine bay with the MMX Performance Billet Washer Fluid Filler Cap — a beautifully engineered solid billet aluminium replacement for the cheap factory plastic cap, finished in MMX's signature gloss black anodising.
Unlike many aftermarket caps that sit over the original, this is a complete OE replacement, arriving pre-sealed to ensure a precise, leak-free fit. CNC-machined using advanced 5-axis technology and finished with the MMX logo, this cap delivers the same level of detail and craft as the wider MMX engine dress-up range.
