Process West Khanacooler (suits Subaru 15-17 VA WRX) (factory flat mount style) - Silver

Our new and highly anticipated ‘straight-fit’ Intercooler, the Process West ‘KHANACOOLER’ is here now. Taking the technology used in our world-leading VERTICOOLER system and integrating it into a conventional Top-Mount setup for ease of fitment and factory-style appearance, KHANACOOLER represents a fantastic first step into the world of Subaru modification.


  • High Flow Process West Bar and plate core measuring 347 x 225 x 100
  • Compatible with factory charge pipe or can you add the Process West charge pipe
  • Comes complete with under hood duct and engine pulley garnish

The good news is that for those of you that value a clean looking engine bay the Process West KHANACOOLER works with the factory duct which means you don’t need to add any unsightly parts to the engine bay to have the whole system working clean and cool.


Rather than gather a single set of data we decided on a two-pronged testing approach for KHANACOOLER to precisely measure and monitor the results of its fitment. First up was the fitment of a latest-spec AIM Data Logging system.

Using data gathered from the AIM Logger we could check how the KHANACOOLER compared to the stock piece under real-world conditions. This way we could measure the effect of heat soak when stationery right through to the not easily simulated wind-load from high speed runs. In each and every test discipline KHANACOOLER showed significant and measureable improvements over stock that you can feel through the seat of your pants when driving.
