Is the cap safe to handle when hot?

The billet aluminium body retains heat, which is why we include the Acetal Key, it locks into the top of the cap allowing you to safely remove it without direct contact.

Can I still use the OEM gasket/seal?

No need, our oil filler caps are all suppliedwith a new sealing O-ring to ensure the perfect seal.

Will this match other 09D engine bay parts?

Absolutely. It follows the same designlanguage and finish as our coolant cap, brake fluid cap, and battery clamp,ideal for a clean and cohesive bay.

Is installation difficult?

Not at all, simply unscrew your existing fillercap and twist the 09D cap into place.
