MMR MMX Performance Billet Oil Filler Cap for BMW OE 11128655331 MMR03-0102-BL

Meticulously machined from billet with the latest CNC 5-axis technology, before being polished, then gloss-anodised to stay beautiful year after year.
It joins our existing range of engine dress-up products for a complete under-bonnet transformation to your engine bay. Our design allows the cap to be installed in a 0 or 90 degree orientation, keeping 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. The 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.

Our MMR cap will fit all engines with the rounded filler cap. Please check the underside of your factory oil cap with the product image to confirm (OE part number 11128655331).
