Premium Alloy Tank Cap Upgrade for Toyota GR Supra A90 A91

Elevate every refuel with a beautifully engineered cap made for the Supra MK5 platform.

It feels substantial in the hand and closes with a satisfying, engineered click every time.

We have fitted and used this on our own cars and for customers, and the feedback is consistently excellent for the look, tactile feel, and premium finish. If you want a quick, high quality enhancement you will notice every time you open the fuel door, this is a standout upgrade for your GR Supra.
