One of the most overlooked steps in upgrading a Subaru intercooler is proper airflow management. Without a correctly sized hood scoop splitter, even the best intercooler upgrade cannot perform at its full potential.

Why It Matters

A larger intercooler core increases cooling capacity—but only when airflow is properly directed:

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

Improper airflow leads to heat soak, rising intake temperatures, and reduced engine performance.

Process West Solution

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

Key benefits include:

• Full airflow coverage across the intercooler surface
• Eliminates air bypass and uneven cooling zones
• Improves charge air temperature stability under load
• Maximizes the effectiveness of upgraded intercooler systems

Designed specifically to complement Process West Top Mount Intercoolers, it completes the airflow system for optimal performance.
