Designed with one goal in mind—to be the best aftermarket top-mounted intercooler for the Subaru Forester, period.

This kit doesn’t just give you a bigger core and call it a day. It addresses the real airflow challenges that limit performance in top-mount setups:

Proper Splitter/Shroud Included:

• Installing a larger intercooler without matching ducting is a waste. That’s why we include a properly sized splitter/shroud, ensuring 100% of the new core sees full ambient airflow for maximum cooling.

Optimized Core Thickness for Maximum Efficiency

• Bigger isn’t always better. Oversized intercoolers restrict airflow, causing heat soak and higher intake temps. The 90 mm (3.5") thick core is engineered for perfect balance—delivering excellent airflow, lower outlet temps, and more consistent power.

Perfect Charge Air Distribution with Silicone Y-Pipe

• The included Process West Silicone Y-Pipe ensures even airflow across the entire intercooler, eliminating the uneven distribution common with other designs.

Features:

• 90 mm (3.5") bar-and-plate intercooler core

• Vehicle-specific splitter/shroud for full airflow coverage

• Premium silicone Y-pipe for consistent charge air distribution

• Complete kit with all required installation hardware

Note: This intercooler kit is designed for use with the JDM STI 2002-2003 WRX Hood Scoop. If using the OEM USDM Forester hood scoop, see SKU PWTMIC08B.
