Description

MMX BMW/MINI 90mm Billet Coolant Expansion Cap is engineered as a complete replacement for the compatible factory cap, not a decorative cover.

Machined from solid aluminium, it delivers a more substantial feel and precise grip while retaining the required direct-replacement cap format.

• Designed around OE cap number 17 11 7 639 021
