Mishimoto Top-Mount Intercooler Kit for 2008-2021 Subaru WRX STI - Stealth Black & Red Hoses (MMTMIC-STI-08BKRD)

Fits 2008-2021 Subaru WRX STI models.

Reduce intake air temperatures and prevent heat soak on your EJ-powered Subaru with the Mishimoto Top-Mount Intercooler (TMIC) Kit. Engineered specifically for the 2008-2021 chassis, this intercooler features a high-efficiency 3.75-inch thick bar-and-plate core with a total volume of 584 in³. The dense offset fin pitch is optimized for maximum heat transfer, supporting vehicles from stock power levels up to 400 whp.

This intercooler utilizes cast aluminum end tanks that are precision TIG-welded to the core for maximum durability under high boost pressures. Testing on a stock vehicle showed a 10°F temperature drop compared to the factory unit, along with bolt-on power gains of +5 whp and +7 wtq. Installation is a direct bolt-on process that requires no modification to the stock A/C lines and can be completed in approximately 30 minutes.
