The Process West Khanacooler is the ultimate "straight-fit" intercooler solution for the VA WRX. Designed for enthusiasts who want world-class cooling without compromising the factory engine bay layout, the Khanacooler integrates the advanced technology of our flagship Verticooler into a traditional top-mount configuration.

Performance Engineering

Built with a high-flow bar-and-plate core, the Khanacooler offers a massive increase in surface area and thermal mass compared to the stock unit. This results in both a significant reduction in intake temperatures and a measurable decrease in pressure drop, allowing your turbo to work more efficiently.

  • Core Dimensions: 347mm x 225mm x 100mm

  • Design: High-flow bar-and-plate construction.

  • Compatibility: Fits perfectly with the factory charge pipe or the upgraded Process West version.

  • OEM Aesthetics: Includes a custom under-hood duct and engine pulley garnish for a professional, "factory-plus" appearance.

Proven Results

We validated the Khanacooler’s performance through rigorous real-world data logging and controlled dyno sessions. Using AIM Data Logging, we monitored heat-soak levels from a standstill up to high-speed wind loads to ensure consistent performance in all driving conditions.

Thermal Efficiency

In back-to-back dyno testing against the OEM intercooler:

  • Factory Outlet Temp: 57°C

  • Khanacooler Outlet Temp: 30°C

  • Improvement: A 27°C (48%) reduction in intake temperatures.

Power & Pressure

Beyond cooling, the Khanacooler reduces boost restriction. Even on a cold run, the core's high-flow design yields immediate power gains by allowing more air to reach the engine with less effort from the turbocharger.

The Bottom Line

Whether you are concerned with pressure drop, temperature management, or simple bolt-on reliability, the Khanacooler delivers. It is a modest 50% upgrade over the factory system, providing a difference you can feel immediately from the driver's seat.

In Pursuit of Something More. 

There's more power under the hood, and the stock intercooler isn’t going to unlock it. Ours will.

Ground-Up Performance Engineering.

Our designs all follow a similar path. We remove the stock cooler and 3D scan the engine bay to determine the precise constraints of the available space. Once we know what we’re working with, we generate functional renders and finalise form, function, and fitment.

Following our digital models, we generate 3D printed prototypes for further, real-world confirmation of size, fitment, and installation ease. When our prototype is perfect, it's on to manufacturing.

Proudly Built Down Under.

All our products are built in-house at our Australian facility. From billet aluminium CNC machining, welding, powder coating and packaging. 

Tested & Independently Verified.

We take our product testing one step further. Every new Intercooler is sent to specialist tuners who confirm installation ease, power gains, and reliability.

Preferred By Record Holders.

You’ll find Process West in some of the quickest and fastest builds in the world, driven by those who only care about one thing. Results.

Pioneers Since 2003.

Process West is built on continuous innovation. We’ve been building intercoolers and innovating airflow dynamics for over 20 years. Every intercooler we develop is designed to set new performance benchmarks in turbocharged builds.
