The Mishimoto intercooler kit for 2013–2018 Ford Focus ST replaces the stock core and piping with a bar‑and‑plate intercooler and mandrel‑bent aluminum piping to improve flow and cooling. It removes the turbo muffler and swaps rubber for wire‑reinforced silicone, yielding a 26% better hot‑side flow and 21% increase overall. Rated to 550 HP and listed to add about 8 HP and 10 lb‑ft when combined with other Mishimoto parts, this kit is available in gold with polished or wrinkle black pipe and is backed by Mishimoto’s lifetime warranty.
