The MMR Performance 90mm billet coolant expansion cap for BMWs has been designed from the ground up in the UK, engineered from a solid billet of aluminium.
Each cap was designed to directly replace the OE cap, not merely a cover stuck in place. Fitment is for models with the matching OE (17 11 7 639 021) part number.
