2008-2021 Subaru STI

The Process West Top Mount Intercooler for the 2008-2014 GRB STI and 2015-2021 VA STI is designed for high-performance Subaru applications that need greater cooling capacity and more consistent power under load.

Featuring Process West’s largest Subaru top-mount core, this kit combines a massive bar-and-plate intercooler with a high-flow silicone Y-pipe for improved charge-air distribution and thermal efficiency.

Key Features & Benefits

  • Massive 530 x 193 x 90mm bar-and-plate core
  • Increased cooling surface area compared with the factory intercooler
  • Helps reduce intake air temperatures and heat soak
  • Supports improved throttle response and more consistent power
  • Process West silicone Y-pipe distributes charge air evenly across the core
  • Complete kit with installation hardware included

High-Capacity Core

The 530 x 193 x 90mm bar-and-plate core provides a significant increase in cooling capacity over the factory intercooler, making it well suited for tuned and higher-output STI builds.

Optimized Y-Pipe Design

The included Process West silicone Y-pipe is engineered to distribute compressed air evenly across the full width of the intercooler core. More balanced airflow helps maximize the effectiveness of the upgraded intercooler instead of concentrating charge air in one section.

What's Included

  • Process West top mount intercooler
  • Process West silicone Y-pipe
  • Required installation hardware and fittings

Great Fitment

Easier to install than stock. I put a larger Rspec turbo on my STI and my stock tmic was touching the vacuum solenoid on the passenger side on the turbo and needed to put spacers under to clear.

The PROCESS WEST was tapered in this area making it a perfect fit.

What a beautiful piece of engineering

Best top mount for your STI. This mod will definitely keep the temperature down and make more sustainable horsepower throughout your time on the track or street without the heat soak from the stock intercooler.

Previous review for wrong part. Solid construction looks great much larger than factory Tam and helps keep temps down
