MMR Billet fuel filler cap for BMW

Nobody likes filling up, right? But, our 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. It makes pumping fuel a little more of a pleasure!

It comes complete with a 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.
