GrimmSpeed Top Mount Intercooler Splitter 2004-2008 Forester XT

Maximize the performance of your GrimmSpeed TMIC with our precision-engineered splitters. Designed to seal perfectly with your top mount intercooler, these splitters increase airflow by 70%, lower outlet temperatures, and enable more aggressive tuning—even on builds producing 600–700 whp. Perfectly distributed airflow ensures your dense intercooler core works efficiently, keeping your charge air cool under heavy loads.

Quick Specs:

• 70% increase in TMIC airflow – maximizes cooling efficiency
• CNC laser-cut 5052 aluminum – lightweight yet durable
• DuPont black powdercoat – OEM+ finish and corrosion resistance
• Custom EPDM rubber gasket – excellent seal and longevity
• CAD-designed vanes and flow simulation – ensures fit and performance
• Supports up to 3 intercooler sprayers – compatible with STI TMIC or custom setups

Design & Materials:
Each splitter is designed in CAD and optimized via flow simulation. Bottom openings and vanes are reworked to distribute air evenly across large GrimmSpeed TMIC cores. Lightweight 20-gauge 5052 aluminum reduces weight by 300% compared to competitors, while flathead rivets replace welds to prevent cracking. The included custom extrusion gasket ensures a secure, long-lasting seal.
