Process West Khanacooler Top Mount Intercooler Silver Subaru WRX 2015-2021 | PWTMIC16

Product Fitment: 

2015-2021 Subaru WRX

The Process West Khanacooler is the ultimate direct-fit top mount intercooler upgrade for the 2015+ Subaru WRX (VA chassis). Designed for enthusiasts who want maximum cooling performance without sacrificing OEM layout, the Khanacooler brings advanced engineering—derived from Process West’s flagship Verti-Cooler—into a true bolt-on solution.

Delivering substantial improvements in airflow, thermal efficiency, and pressure drop, the Khanacooler is the perfect upgrade for both daily-driven and performance-focused WRX builds.

Performance-Focused Engineering

At the core of the Khanacooler is a high-flow bar-and-plate intercooler core, significantly increasing cooling capacity over the factory unit.

Core Specifications:

• 347mm x 225mm x 100mm
• High-flow bar-and-plate construction

This design provides:

• Increased thermal mass for heat absorption
• Reduced intake air temperatures
• Lower pressure drop for improved turbo efficiency

OEM Fitment with Enhanced Design

The Khanacooler is engineered as a true straight-fit upgrade, maintaining factory compatibility while improving performance:

• Direct fit with factory charge pipe or Process West upgrade
• Includes custom under-hood ducting for optimized airflow
• Features engine pulley garnish for a clean, factory-style appearance

This ensures seamless installation and an OEM+ finish under the hood.

Proven Thermal Performance

Extensive testing through real-world data logging and dyno sessions confirms the Khanacooler’s effectiveness:

Back-to-Back Dyno Testing:

• Factory Intercooler: 57°C outlet temp
• Khanacooler: 30°C outlet temp
• Improvement: 27°C reduction (48% decrease)

This dramatic drop in intake temperatures results in more consistent performance and reduced heat soak.

Improved Power & Efficiency

Beyond cooling, the Khanacooler reduces airflow restriction:

• Lower pressure drop across the core
• Increased airflow to the engine
• Improved turbo efficiency
• Immediate gains in throttle response and power delivery

Even under light load, the improved flow characteristics provide noticeable performance benefits.

The Bottom Line

The Process West Khanacooler delivers a balanced, high-performance upgrade—combining strong cooling gains, improved airflow, and effortless installation. With roughly a 50% performance improvement over the factory system, it’s a difference you can feel every time you drive.
