Say hello to our intercooler for the 2016-2018 Ford Focus RS! Whether you are a track junkie, occasionally taking your RS for some spirited driving, or making your RS a car to steal the show, this intercooler will suit your needs. Our intercooler has been beefed up with a 36% increase in core volume and a 214% increase in external fin surface area, which means increased air-cooling efficiency for your RS. Our core reduces air outlet temperature by almost 40% while minimizing the inlet/outlet pressure drop across the core, and provides gains of 7hp and 8ft-lbs! This hefty, direct-fit, bar-and-plate core is durable enough to withstand any type of abuse you throw at it, while improving the heat transfer process both at idle and cruising speeds. This intercooler is designed to function with all factory equipment on the 2016-2018 Focus RS as well as our upgraded intercooler pipes. There is no modification necessary for installation, making it a true bolt-on performance part. As with all our parts, this intercooler comes with the Mishimoto Lifetime Warranty. Order yours today!
