Overview

It addresses common design flaws found in other intercoolers, such as undersized ducting and cores that are too thick. This intercooler features a 90mm thick core, which balances cooling surface area with airflow resistance.
Show original supplier description
The Process West Top Mount Intercooler was developed with the goal of being the ultimate aftermarket top mount intercooler for the WRX and STI. It directly addresses common issues like inadequate ducting that fails to provide airflow to the entire intercooler core and excessively thick cores that restrict airflow and hinder heat exchange. The Process West core is optimized at 90mm thick, striking the ideal balance between surface area and airflow resistance, which is reflected in lower outlet temperatures and improved power figures. It features a bar and plate construction. **Note:** The Intercooler Splitter specifically does not fit the 04-05 STI models.
