Process West Top Mount Intercooler (STi 08-21) Black

Process West Top Mount Intercooler (STi 08-21) – Black

Application: Subaru STi 2008–2021

Part Number: PWTMIC06B

The Process West Top Mount Intercooler is the definitive bolt-on cooling upgrade for the Subaru STi. Engineered to replace the restrictive factory top mount intercooler, this unit dramatically improves charge air cooling efficiency — keeping intake temperatures lower under sustained hard driving and delivering more consistent power throughout your pulls.

Finished in a stealthy satin black powder coat, the PWTMIC06B is built from a high-density bar-and-plate core that offers significantly greater thermal capacity than the OEM unit. The result is reduced heat soak, improved throttle response, and more reliable power delivery whether you're on the street or the track.

The kit includes all necessary silicone hoses, clamps, and hardware for a complete bolt-on installation — no cutting, drilling, or fabrication required. Designed and manufactured in Australia by Process West, this intercooler is engineered specifically for the STi platform and is trusted by tuners and enthusiasts across the country.
