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 gas 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.
