TURBOXS Front Mount Intercooler Kit (2015-2021 Subaru WRX STi)

One of the biggest keys to making consistent power in a 2015+ STi is managing the intake manifold temperature. This is an issue when the STi 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 due to the hotter, less dense air coming out of the intercooler. You could replace the stock TMIC with a well-designed aftermarket TMIC. While they are certainly much better than the stock TMIC, they can only delay the inevitable intake manifold temperature increase that comes from having a small intercooler core sitting inside a hot engine bay.

Enter the TurboXS Front Mount Intercooler for the 2015+ STi. The bar and plate core is 28 inches wide, 8 inches tall, and 3.75 inches thick and absolutely dwarfs the factory TMIC. With our FMIC installed on a 2015+ STi, intake manifold temperatures stay constant even after repeated pulls to redline. With the TurboXS Front Mount Intercooler, inconsistent power output due to sky-high intake manifold temperatures is a thing of the past!

In addition to performing the design function of cooling the intake charge flawlessly, our FMIC includes some cool features such as a powder coated tubular steel mounting beam with integrated threaded tow hook mount. This unique feature allows you to use any License Plate Relocation kit that uses the tow hook mount such as our TOWTAG-W15 (sold separately). This keeps you legal while also keeping your front license plate from blocking airflow to your FMIC. No other FMIC on the market that we know of has this unique, one-of-a-kind feature! Please note that this mount is NOT designed to tow the car. It should be used for license plate relocation only.
