Process West Front Mount Intercooler Subaru Impreza WRX / STI 1997-2001 | PWFMIC01

Product Fitment: 

• 1997-2000 Subaru WRX

• 1997–2000 Subaru STI

or JDM WRX and STi Model GC's

Take your GC8 to the next level with the Process West Front Mount Intercooler Kit, widely regarded as a benchmark cooling upgrade for 1997–2000 Subaru WRX and STI models. Designed to handle real-world performance demands, this system delivers consistent power, reduced heat soak, and improved throttle response—far beyond the limits of the factory top mount intercooler.

Why Upgrade from the Factory Intercooler?

The stock GC8 intercooler is sufficient for factory power levels, but once you begin pushing the car—whether through spirited driving, track use, or tuning—heat soak quickly becomes a limiting factor. Rising intake temperatures reduce engine efficiency, forcing the ECU to pull timing and resulting in inconsistent performance.

Superior Cooling Performance

At the core of this system is a large 600 x 285 x 100mm bar-and-plate intercooler core, paired with high-flow polished aluminum end tanks. This significantly increases cooling surface area and efficiency, allowing for lower intake air temperatures and more oxygen-dense air entering the engine.

The result:

• More consistent horsepower across the RPM range

• Improved throttle response

• Safer and more reliable tuning potential

• Reduced heat soak during aggressive driving

Mandrel-Bent Aluminum Piping

The kit features mandrel-bent aluminum intercooler piping, ensuring smooth, unrestricted airflow throughout the system. Unlike crush-bent alternatives, mandrel bending maintains a consistent diameter through every curve, eliminating airflow bottlenecks and maximizing efficiency.
