Process West Front Mount Intercooler Black Subaru Impreza 1997-2001

The Process West Front Mount Intercooler Kit is a benchmark cooling upgrade for the 1997–2000 Subaru GC8 WRX and STI. Engineered to unlock the full potential of the platform, it delivers consistent charge-air cooling that the factory intercooler cannot maintain under demanding real-world conditions.

Why the Factory Intercooler Falls Short

The stock GC8 intercooler performs adequately at standard power levels, but under harder driving conditions—such as spirited mountain runs, track use, or tuned setups—it quickly becomes heat-soaked.

As intake air temperatures rise:

• Engine power is reduced
• Throttle response becomes less sharp
• ECU timing is pulled to protect the engine

The result is inconsistent performance precisely when you need it most.

Superior Cooling, Consistently

The Process West intercooler core measures:

600 x 285 x 100mm (bar and plate construction)

This significantly increases cooling surface area compared to the factory unit, allowing for:

• Lower intake air temperatures
• Denser, more oxygen-rich charge air
• More consistent power delivery across the rev range
• Improved throttle response
• Safer, more reliable tuning potential

Whether on the street or track, this system maintains stable intake temperatures where the factory unit cannot.

Mandrel Bent Aluminium Piping

The kit includes full mandrel-bent aluminium piping designed to maximize airflow efficiency.

Key benefits:

• Smooth, unrestricted airflow path
• Consistent pipe diameter through bends
• Eliminates flow restriction caused by crush-bent piping
• Improved turbo efficiency and response
