MMR Performance BMW Billet Oil Filler Cap
The MMR Performance billet oil filler cap for all BMW B58 I N54 I N55 I S54 I S55 I S63 makes topping up your oil a pleasure! 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.
It joins our existing range of engine dress-up products for a complete under-bonnet transformation to your engine bay. We've now updated our design to allow the cap to be installed in a 0 or 90 degree orientation - to keep the cap aligned to either longitudinal or transverse engine installations.
Never again will you worry whether you tightened your oil cap fully - as our 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.
Each 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.
The carefully considered design gives ample surface grip area for your fingers, making installation and filling your engine oil that little bit easier.
This Oil Filler Cap will fit all engines with the rounded filler cap and same underside as shown in product images. Please check the underside of your factory oil cap with the product image to confirm (OE Part Number 11128655331).
