Mishimoto's gold intercooler kit for 2013–2018 Ford Focus ST includes an upgraded bar-and-plate core with black piping and gold intercooler finish. The kit replaces restrictive stock piping with mandrel-bent aluminum and wire-reinforced silicone, boosting hot-side flow by 26% and overall intercooler flow by 21%. It improves cooling efficiency under demanding conditions and, with related upgrades, yields roughly 8 HP and 10 lb-ft while carrying Mishimoto's lifetime warranty.
