Nobody likes filling up, right? But our new Billet Fuel Filler Cap is beautifully over-engineered in customary MMR fashion to give an exquisite feel and beautiful appearance every single time you use it. Makes pumping petrol a little more of a pleasure!
Make refuelling great again! MMR Performance’s replacement Billet Fuel Cap is one of those upgrades that will delight you every time you fill your tank. Machined from a solid billet aluminium, it’s lovingly hand-polished then anodised in glossy midnight black with laser-etched logo.
It closes with a satisfying engineered 'click' each time you fill up.
The design still allows you to prop the cap in the factory locater in the filler flap while you're filling up. And it comes complete with new rubber o-ring seal and locating tether to match all the functionality of the plastic factory cap.
Each cap starts life as a solid billet of 6061 aerospace-grade aluminium. After being meticulously machined with the latest CNC 5-axis technology it’s then polished and gloss-anodised Midnight Black to stay beautiful year after year.
Comes complete with new rubber o-ring seal and locating tag to match all the functionality of the plastic factory cap. Meanwhile a new pressure relief valve integrated into the cap always maintains balanced tank pressure.
One of the simplest but most pleasing upgrades you can make to your car!
This filler cap will fit all BMW models from 1997 onwards & all Mini F5x, F6x and R5x models from 2007+
