TurboXS Front Mount Intercooler Kit Polished 2015-2021 WRX

The TurboXS 2015+ Subaru WRX Front Mount Intercooler Kit might be the single best modification you can do to your 2015-2016 WRX.  One of the biggest keys to making consistent power in a 2015+ WRX is managing the intake manifold temperature.  This is an issue when the WRX is bone stock and becomes an even bigger issue when you start to modify it.  The stock top mount intercooler simply isn’t up to the task.  After just a few minutes of hard driving, the small, overworked TMIC quickly becomes heat soaked.  Intake manifold temperatures rise quickly and power output drops off even more quickly.  The power drop is not just due to the hotter, less dense air coming out of the intercooler but also because the WRX ECU logic will actually start to reduce ignition timing as intake manifold temperatures climb.  Reduced ignition time directly reduced power output.  You could replace the stock TMIC with a well-designed aftermarket TMIC.  While they are certainly much better than the stock TMIC, our testing shows that even they can only delay the inevitable intake manifold temperature increase that comes from having a small intercooler core sitting inside a hot engine bay.
