GrimmSpeed Top Mount Intercooler Splitter 2002-2007 WRX/STI

  • This intercooler splitter is custom-designed for the 2002-2007 STI. It directs air to your GrimmSpeed upgraded top-mount intercooler (TMIC) core. Rubber gasketing ensures a good seal to the intercooler. Vent area allows the turbo to shed heat.


    • 70% Increase in flow capacity to your TMIC - Massively improves your TMIC's ability to remove heat
    • Maximizes TMIC Efficiency - Lowers TMIC outlet temps, enables more aggressive tuning
    • Designed for even flow distribution - Forces entire core work to cool the hot charge air
    • CAD design and simulation - Ensures both fitment and function
    • CNC Laser Cut 5052 Aluminum - Resists fatigue due to heat and vibration
    • Durable DuPont Black Powdercoat - Protects splitter with an OEM finish
    • Custom EPDM Rubber Gasket - Provides excellent seal and longevity
    • 3x Intercooler Sprayer Ports - Utilize your STI TMIC sprayer or add one if you'd like
