09 Design HVF Performance Intercooler Upgrade – Ford Fiesta ST Mk8/8.5
Unlock cooler, denser intake air for your Mk8 or Mk8.5 Fiesta ST with the 09 Design HVF intercooler. It cuts charge temperatures to help the engine make strong, repeatable power on the road or track, especially during hard use or warm weather.
The high-performance bar-and-plate alloy core is 107% larger than stock. Paired with high-flow cast end tanks, it moves air efficiently with minimal pressure drop, so you keep response while gaining cooling. Lower intake temps reduce heat soak and help protect against knock for safer, more consistent performance.
This upgrade fits with the factory intercooler pipework and requires no cutting to existing parts. Installation is straightforward and uses standard mounting points. It works well on standard cars and tuned setups alike.
Designed specifically for the Ford Fiesta ST Mk8 and Mk8.5. Please use our vehicle lookup to confirm fitment or check the Vehicle Fitment tab for full details.
