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.

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.
Upgrading to a larger intercooler core increases cooling capacity—but only if airflow is properly directed:
Without proper sealing, heat soak increases and intake air temperatures rise—directly impacting power and consistency.
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:
Designed specifically to pair with Process West Top Mount Intercoolers, it completes the airflow system for optimal cooling efficiency.
