Product Fitment:

2004-2007 Subaru WRX

One of the most overlooked steps in upgrading a Subaru intercooler is ensuring proper airflow management. Without a correctly sized hood scoop splitter, even the best intercooler upgrade will struggle to perform as intended.


Why It Matters

Upgrading to a larger intercooler core increases cooling capacity—but only if airflow is properly directed:

  • Factory splitter retained: Limits airflow coverage across the larger core
  • Splitter removed: Air bypasses the intercooler, reducing cooling efficiency
  • Correct splitter installed: Forces air directly through the intercooler for maximum performance

Without proper sealing, heat soak increases and intake air temperatures rise—directly impacting power and consistency.


Process West Engineering Solution

The Process West Hood Scoop Splitter is designed to create a complete seal between the hood scoop and intercooler core, ensuring all incoming air is forced through the intercooler.

Key benefits include:

  • Maximizes airflow through the entire intercooler surface
  • Eliminates air bypass and uneven cooling zones
  • Improves charge air temperature control under load
  • Enhances consistency during aggressive driving or track use

Designed specifically to pair with Process West Top Mount Intercoolers, it completes the airflow system for optimal cooling efficiency.

Works as described

I installed an STI intercooler, and this hood scoop splitter works flawlessly to direct the air directly into the larger STI intercooler. It’s easy to install right where the stock one is.

Import Image Racing does it again!

So I've already gotten my hands on the Process West intercooler from Import Image Racing when just about nobody else around had it, while at the same time chasing this shroud. In stock dates for the shroud were in January at earliest. ***Jeremy Clarkson voice*** AND THEN........Import Image Racing magically makes a good number of these shrouds appear almost out of thin air. I grabbed one immediately. NO RAGRETS!! (Not even a single letter) Thank you once again Import Image Racing for delivering what I was searching for, and unbelievably fast shipping!!
