Provides a beautiful complete replacement for your factory plastic cap to really smarten up the under bonnet visuals.
The MMX Performance billet washer bottle cap for F-Series BMWs has been designed from the ground up in the UK, constructed from a solid billet of aluminium.

Our replacement washer bottle cap is beautifully over-engineered to give an exquisite feel and exceptional product experience compared to OE. A beautiful complete replacement for your factory plastic cap to really smarten up the under-bonnet visuals.

The MMX washer fluid cap arrives pre-sealed for a precise and leak-free connection. Each cap was designed to directly replace the OE cap, not merely a cover stuck in place.

It's meticulously machined from this billet with the latest CNC 5-axis technology, before being polished, then gloss-anodised to stay beautiful year after year.
