Durable Pro Alloy Focus Mk3 St & Rs Alloy Header Tank Now 85% Cheaper [pfsKLt0x]

Elevate the performance and aesthetics of your Focus MK3 ST or RS with Pro Alloy's custom-made header tanks. Designed with precision and crafted for durability, these header tanks are the perfect upgrade for your engine bay.

Engineered Excellence

Pro Alloy's design team meticulously crafted these header tanks using a 3D CAD model, ensuring a perfect fitment and appearance in the RS engine bay. The tanks are made from pressure-tested, durable aluminium, offering a significant upgrade over the original plastic parts. With CNC machined mounting pins and filler necks, laser-cut mounting brackets, and TIG welding by skilled engineers, these header tanks are built to last.
  • Pressed aluminium body for strength and longevity
  • Pressure tested to ensure reliability

Customization and Convenience

Available in a range of finishes, from subtle satin black powder-coat to mirror polished, these header tanks cater to your personal style and show car needs. Each tank comes with a fitting kit, including all necessary parts for installation. With a "sight glass" feature, checking fluid levels is a breeze. This direct replacement for the OEM tank is compatible with all mk3 Focus models, including ST and RS, making it an ideal upgrade for any enthusiast.
  • Available in multiple finishes to match your car's style
  • Complete fitting kit included for easy installation
