Process West Front Mount Intercooler Kit Black Subaru STI 2008-2014 | PWFMIC03B

Product Fitment: 

2008-2014 Subaru STI

The Process West Front Mount Intercooler Kit is a benchmark cooling upgrade for the 2008–2014 Subaru STI (GRB chassis). Engineered to unlock the platform’s full potential, it delivers consistent charge-air cooling and thermal stability that the factory intercooler cannot maintain under demanding real-world driving conditions.

Why the Factory Intercooler Falls Short

The stock GRB STI intercooler performs adequately at factory power levels, but under sustained load—such as spirited driving, track use, or tuning—heat soak becomes a limiting factor.

As intake air temperatures rise:

• Engine power decreases
• Throttle response becomes less responsive
• ECU timing is reduced to protect the engine

The result is inconsistent performance when sustained power is needed most.

Superior Cooling, Consistently

The Process West intercooler features a 620 x 255 x 90mm bar and plate core, designed to significantly improve thermal efficiency over the factory unit.

This results in:

• Increased cooling surface area
• Lower intake air temperatures
• More oxygen-dense charge air
• More consistent power delivery across the rev range
• Improved throttle response
• Enhanced tuning stability and safety margin

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

Mandrel Bent Aluminium Piping

The kit includes full mandrel-bent aluminium intercooler piping, engineered for optimal airflow efficiency.

Benefits include:

• Smooth, unrestricted airflow path
• Consistent pipe diameter through bends
• Reduced turbulence and restriction
• Improved turbocharger efficiency and response
