The Perrin Front Mount Intercooler (FMIC) kits for the 02-09 WRX & 04-09 STi is a massive upgrade. Designed for 500hp to 800hp applications, Perrin's enormous bar and plate intercooler core will not disappoint. Cast aluminium endtanks and a high-flow core ensure even airflow and an optimized intake charge. Perrin's WRX/STi FMIC kits mount to a (supplied) powdercoated boxed steel replacement bumper beam with 1/2" thick mounting plates, so there is no cutting of the stock structural components required. While exceptionally sturdy, this beam is designed for off-road use only.

Perrin's front mount intercoolers are available with high-polished, red powdercoated aluminium (Signature Series), or black powdercoated aluminium (Steath Series) components.  The kit includes all the necessary silicone connectors, T-bolt clamps, as well as a silicone coolant reservoir. The intercooler boost tube also includes a triangular flange for a stock-style blow off valve (BOV) positioned to reuse the stock recirculation tube.
