The MMX Performance billet oil filler cap for BMW S58 and B48E engines has been designed from the ground up in the UK, from a solid piece of billet aluminium.
Each cap is designed to directly replace the OE cap, not merely stuck in place.
Each MMX cap starts life as a solid billet of 6061 aerospace-grade aluminium. 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.
All MMX oil caps arrive pre-sealed and pre-installed with an OE spec valve and internal spring. No need to remove the assembly from your OE cap. A true plug and play solution.
It has been designed to instantly give your BMW an under-bonnet boost in the aesthetic department, finished in a deep gloss black anodised finish.
Never again will you worry whether you tightened your oil cap fully, as the internally sprung cap clicks hard and locks into place. This cap will ensure that you'll never again have the problem of 'weeping' oil leaks from the standard cap - a known issue with many of these engines as age and mileage causes them to deteriorate.
It joins an existing range of engine dress-up products for a complete under-bonnet transformation to your engine bay.
The carefully considered design gives ample surface grip area for your fingers, making installation and filling your engine oil that little bit easier.
