Engineered for rapid air-charge cooling and maximum flow-path efficiency, the Process West Verti-Cooler is a revolutionary approach to Subaru intercooler design. This innovative system dramatically improves turbocharger cooling, delivering unmatched performance and enhanced engine durability.

Unlike traditional top-mount or front-mount setups, the Verti-Cooler positions the intercooler vertically for optimal airflow and heat exchange, reducing heat soak and ensuring consistent power delivery.

Verti-Cooler combines the advantages of a large and free-flowing Process West core (400mm flow length, 205mm stack height, 120mm thick) with a design that mounts the new intercooler at a 15 degree, near vertical angle in the engine bay. Packaged with a new hood duct design that force-feeds external airflow straight onto the intercooler fins, there is now a highly efficient air exit path courtesy of the Verti-Cooler mounting angle that flows all of this (now heated) air back down through the engine bay and out the underside of the car through the transmission tunnel for a shallow, cool, and low restriction exit-path. Compare then the near on 90 degree angle that the air must turn with the stock intercooler setup in place, and the advantages of the Process West Verti-Cooler design become clear. Verti-cooler also has the largest volume of any aftermarket intercooler for the 2015-2021 WRX with core measurements of 400mm flow length x 205mm stack height x 120mm thick.

In true Process West fashion, everything you need is included:

• Verti-Cooler Intercooler Body – advanced bar-and-plate design for superior heat dissipation

• Vehicle-Specific Under-Hood Air Duct/Splitter – directs airflow for maximum cooling efficiency

• Form-Fitted Silicone Hoses – designed for perfect fitment and durability

• High-Quality Constant Tension Hose Clamps – secure connections for long-term reliability
