Compatible with a wide range of Ford models, the billet coolant cap is packed with 09Design touches as you might expect, from the knurled body, to the intricate top section… but there’s much more to this cap than meets the eye. Designed and manufactured in the UK from CNC-machined aerospace-grade billet aluminium, with an optional temperature stable key-operated opening and closing system, adding a new layer of functionality and convenience... Features Crafted in‑house from T6082 aluminium for precision, durability, and a premium finish. Corrosion resistant and visually striking thanks to an anodised gloss black finish, giving a high‑end engine bay accent. Functional knurling around the cap body improves grip, even with gloves or oily hands. Subtle, crisp branding that matches the rest of your 09D engine bay accessories. Use with the optional 09D Acetal Key Tool (available to purchase separately here) for easier opening when hot, protecting your hands and enhancing convenience. Designed to match our oil filler and brake fluid caps for a clean, cohesive look.
