Each cap was designed to directly replace the OE cap, not merely stuck in place. 90mm fitment replaces OE part number 17117639021 while 60mm fitment replaces OE part number 17117639024.\u003c\/p\u003e\u003cp\u003eEach MMR cap starts life as a solid billet of 6061 aerospace-grade aluminum. It's meticulously machined from this billet with the latest CNC 5-axis technology, before being polished, then gloss-anodized to stay beautiful year after year.\u003c\/p\u003e\u003cp\u003eAll MMR coolant caps arrive pre-sealed and pre-installed with an OE spec valve and internal spring. No need to remove the valve assembly from your OE cap. A true plug and play solution.\u003c\/p\u003e\u003cp\u003eIt has been designed to instantly give your BMW an under-bonnet boost in the aesthetic department, finished in a deep gloss black anodized finish.\u003c\/p\u003e\u003cp\u003eNever again will you worry whether you tightened your expansion cap fully, as the cap contains complete OE replacement internals. The carefully considered design gives ample surface grip area for your fingers, making installation and filling your coolant that little bit easier.\u003c\/p\u003e\u003cp\u003eIt joins an existing range of engine dress-up products for a complete under-bonnet transformation to your engine bay.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eNOTE:\u003c\/strong\u003e Caps sold individually.
