Process West Top Mount Intercooler w/ Shroud For 2004-07 Subaru Forester XT (Black)

Note: Designed for use with the 2002 STi High-Flow Bonnet Scoop

The goal for the Process West Top Mount Intercooler (TMIC) was simple: to engineer the best-performing aftermarket top-mount on the market. By analyzing common industry failures—such as poor ducting and inefficient core thickness—we have developed a cooling solution that sets a new standard for the Subaru platform.

The Critical Factor: Proper Ducting

A common mistake in the aftermarket is supplying a larger intercooler without the necessary ducting to support it. Installing a massive core while retaining the factory under-bonnet shroud is a waste of resources; the factory shroud simply cannot distribute air across the increased surface area.

Optimised Core Thickness: 90mm vs. 114mm

Many competitors market 114mm (4.5") cores based on the "bigger is better" philosophy. However, for a top-mount application where air must make a sharp 90-degree turn through a bonnet scoop, excessive thickness creates too much resistance.

• Our Design: We utilize a 90mm (3.5") core.
• The Result: This thickness allows the air to actually "breathe" through the core rather than hitting a wall of resistance. This results in lower outlet temperatures and more consistent power.

High-Flow Silicone Y-Pipe

Standard aftermarket Y-pipes often suffer from uneven air distribution, favoring one side of the intercooler. Our custom-molded silicone Y-pipe is designed for perfect charge-air distribution across the entire entry tank.

Real-World Street Testing
The true test happens on the road. During spirited mountain driving:

• Stock Intercooler: Temperatures peaked at 72°C and continued to rise, resulting in a noticeable loss of engine "liveliness."
• Process West System: Despite aggressive driving, outlet temperatures never exceeded 43°C.
