One of the most commonly overlooked components in a Subaru intercooler upgrade is the hood scoop splitter. Without a properly sized and sealed splitter, even a high-performance intercooler cannot operate at its full potential.

Why It Matters

A larger intercooler core increases thermal capacity, but airflow management determines real-world performance:

• Factory splitter retained: Limits airflow coverage across the upgraded core
• No splitter installed: Air bypasses the intercooler entirely, increasing heat soak
• Correctly sized splitter: Forces 100% of incoming air through the intercooler core

Process West Solution

The Process West Hood Scoop Splitter is engineered to eliminate airflow inefficiencies by creating a precise seal between the hood scoop and intercooler core.

Key benefits include:

• Directs all incoming air through the intercooler core
• Eliminates airflow bypass and dead zones
• Improves charge air temperature control under load
• Maximizes efficiency of upgraded intercooler systems

It is designed specifically to complement the Process West Top Mount Intercooler system, ensuring the entire cooling package works as intended.
