Elevate the appearance of your Ford Mustang's engine bay with the GT101 Billet Aluminium Oil Filler Cap, a premium replacement for the original factory component, designed specifically for the S550(FN) and S650 generation Mustang.
Designed and manufactured in T6-6082 billet aluminium by our sister company 09Design right here in the UK, this beautifully engineered oil filler cap combines exceptional craftsmanship with a distinctive, motorsport-inspired aesthetic. Every detail has been carefully considered, from the precision-machined surfaces and intricate detailing to the deeply knurled outer edge, providing both an unmistakably premium appearance and a secure grip during removal and installation.
Finished in a sleek black anodised coating, the cap features distinctive GT101 branding and precision-engraved detailing, creating a subtle yet striking upgrade that perfectly complements the Mustang's engine bay.
Engineered as a direct replacement for the original Ford oil filler cap, the GT101 billet aluminium alternative offers straightforward installation without modification, retaining the convenience and functionality of the factory component.
The GT101 Billet Engine Oil Cap replaces the standard cap and installs directly in its place.
Never attempt to remove the oil filler cap while the engine is running - leave to cool before opening, or use our optional acetal key tool.

The Mustang's engine bay contains plenty of plastic components from the factory, making the engine oil filler cap an easy but effective area to add a more considered finishing touch.
The understated black anodised finish has been chosen to complement the surrounding factory components rather than overpower them, while the machined detailing and GT101 branding provide a finish appropriate for everything from a standard road car to a comprehensively modified Mustang.
Installation couldn't be simpler: remove the original engine oil filler cap and replace it with the GT101 billet version. No modifications, tools or permanent changes to the vehicle are required.
