Process West Top Mount Intercooler – Subaru GC8 WRX/STI (97–98) – Black

The Process West Top Mount Intercooler Kit for the 1997–1999 Subaru WRX and STI (GC8) is engineered to be the most effective and complete top mount intercooler upgrade available. With a massive core and properly matched airflow ducting, this kit delivers unmatched cooling performance and airflow efficiency.

Unlike other aftermarket TMICs that rely on the factory under-bonnet splitter, Process West developed a dedicated bonnet splitter/shroud specifically designed to suit the larger core. This ensures 100% coverage of the intercooler face, directing ambient air across the entire surface for consistent and effective cooling.

With a massive 175mm (H) x 490mm (W) x 90mm (T) bar-and-plate core, this is the largest top mount intercooler on the market for the GC8 platform — making it ideal for both street and motorsport applications.
