It's time to make your cool off your hot - hatch with the Mishimoto Performance Intercooler Kit for the 2013 - 2018 Ford Focus ST. Ford released their 2.0T EcoBoost powered Focus boasting the perfect combination of performance and practicality, however the intercooling system left something to be desired. While the piping did feature sections of aluminum, the restrictive diameter, not to mention the turbo muffler put a damper on the Focus STs performance potential. We've replaced the hot - side pipe with mandrel - bent aluminum, both ditching the muffler and also opening up the diameter to allow a 26 - percent better flow through the hot - side. All of the degradation - prone rubber has also been swapped for wire - reinforced silicone ensuring a long lasting connection on the hot - side, but also a soother flow through the cold - side pipe. Together the Focus ST Intercooler Pipe kit grants a 21 - percent increase in flow to and from the intercooler. The piping isnt the only part of this kit that increases flow, the bar - and - plate construction opens up air channels within the core allowing for the charged air to pass through more freely than the stock intercooler core. This upgraded all aluminum construction also aids in heat dissipation, warding off the dreaded heat - soak under demanding driving conditions, and delivering properly cooled air through the STs intake manifold. The Focus ST Performance Intercooler Kit will also add 8 HP and 10 TQ to your power band and has a maximum horsepower rating of 550HP. The Mishimoto Performance Intercooler Kit for your 2013 - 2018 is available in silver, black, or gold, with an option of wrinkle black or polished piping. As always, this intercooler kit is covered under the Mishimoto Lifetime Warranty.
