Process West Top Mount Intercooler Black 1999-2000 WRX / 1999-2000 STI Shop Now

Description

Note: This intercooler is designed for the JDM 1999-2000 WRX / STI models.

The Process West Top Mounted Intercooler (TMIC) for the GC8 WRX/STI (MY97–MY99) was engineered with a single goal in mind: to deliver the best-performing aftermarket TMIC available for this platform.

Unlike other options on the market, Process West didn’t just make the core bigger—they solved the airflow problem that many people overlook. Installing a larger intercooler while retaining the factory under-hood splitter is ineffective, as it fails to channel sufficient airflow across the full surface of the core.

The solution? A complete system that includes a properly sized under-bonnet splitter/shroud designed specifically for the larger intercooler. This ensures 100% ambient airflow coverage across the entire core, maximizing cooling efficiency and performance.

Features:

• Massive Core Size: 175mm (H) x 490mm (W) x 90mm (T) – the largest TMIC available for the GC8.

• Optimized Airflow: Includes a custom-fitted splitter/shroud for full core coverage.

• Superior Cooling Performance: Reduces heat soak and maintains consistent intake temps for maximum power.

• Direct Fitment: Designed specifically for MY97–MY99 Subaru WRX/STI.

When combined with the under-bonnet splitter, the Process West TMIC offers unmatched performance and reliability, making it the ultimate upgrade for your GC8.
