Khanacooler Top Mount Intercooler 347x225x100mm

The Process West Khanacooler is the ultimate direct-fit top mount intercooler upgrade designed for the 2015+ Subaru WRX (VA chassis). This intercooler delivers substantial improvements in airflow, thermal efficiency, and pressure drop, making it an ideal upgrade for both daily-driven and performance-focused WRX builds. At its core, the Khanacooler utilizes a high-flow bar-and-plate intercooler core, significantly increasing cooling capacity over the stock unit. Its specifications include a core size of 347mm x 225mm x 100mm, offering increased thermal mass for heat absorption, reduced intake air temperatures, and lower pressure drop for improved turbo efficiency. The design ensures a true straight-fit upgrade, maintaining factory compatibility with features like direct fit with the factory charge pipe or Process West upgrades, custom under-hood ducting for optimized airflow, and an engine pulley garnish for a clean, factory-style appearance. Extensive testing has confirmed the Khanacooler's effectiveness, with back-to-back dyno testing showing a reduction in outlet temperature from 57°C (factory) to 30°C (Khanacooler), a 27°C reduction or 48% decrease. This dramatic drop in intake temperatures leads to more consistent performance and reduced heat soak. Beyond cooling, the Khanacooler also reduces airflow restriction, resulting in lower pressure drop across the core, increased airflow to the engine, improved turbo efficiency, and immediate gains in throttle response and power delivery. Even under light load, the improved flow characteristics provide noticeable performance benefits. While generally an easy install, some users have noted fitment can be tight. One user reported that for 2018 models, a design change required minor drilling for the provided splitter to fit properly. Additionally, one reviewer experienced issues with the provided hose clamps and hose blowing off under boost, suggesting alternative solutions like T-clamps or that the coupler might be too small and require significant effort to install on the throttle body and intercooler.
