Looking for a MINI Cooper fuel cap replacement? Whether your factory cap has gone loose, won't seal properly, or the tether has snapped, this billet aluminum replacement covers nearly every MINI Cooper ever built - R55 through the newest Gen 4 cars - plus a wide range of BMW models.

Not a Cover - A Full Replacement

This is a complete mechanical replacement, not a cosmetic skin or adhesive overlay. It installs using the factory OEM mounting interface, retains the factory tethered mechanism so it stays attached during refueling, and seals and locks exactly like the original.

How It's Made

5-axis CNC machined from solid aluminum billet, anodized for corrosion and wear resistance, then hand-polished. The profile references the mechanical fuel caps found on period racing and GT cars. For the full material story, see why billet aluminum fixes a loose or stuck fuel door.
