GrimmSpeed Hood Scoop TMIC Splitter – 2002–2003 Subaru WRX (GD Bug-Eye)

Improve the intercooler efficiency of your 2002–2003 Subaru WRX's top-mount intercooler with the GrimmSpeed Hood Scoop TMIC Splitter. The GD bug-eye WRX uses a hood scoop to feed ambient air to the top-mount intercooler — but the factory scoop-to-TMIC airflow path is inefficient, allowing a significant portion of the incoming air to bypass the intercooler core rather than flowing directly through it. GrimmSpeed's TMIC splitter installs inside the hood scoop and directs incoming airflow more precisely and efficiently into the TMIC core, reducing charge air temperatures, minimizing heat soak, and improving intercooler effectiveness — a meaningful upgrade for any GD WRX build running the factory or upgraded TMIC.

Key Features

• Improved Scoop-to-TMIC Airflow: Directs hood scoop airflow more precisely into the TMIC core — reduces airflow bypass around the intercooler for improved cooling efficiency and reduced charge air temperatures
• Reduced Heat Soak: More efficient airflow through the TMIC core means lower and more consistent charge air temperatures — reduced heat soak for more consistent power output
• GD Bug-Eye WRX Specific: Engineered specifically for the 2002–2003 Subaru WRX (GD, bug-eye) hood scoop and TMIC configuration
• Factory & Upgraded TMIC Compatible: Works with the factory GD WRX TMIC and compatible aftermarket top-mount intercooler upgrades that retain the scoop-fed configuration
• GrimmSpeed Quality: Manufactured by GrimmSpeed — a trusted name in Subaru performance parts with a proven track record on the WRX and STI platforms

Note: Specific to the 2002–2003 GD bug-eye WRX hood scoop configuration — verify fitment for your specific GD WRX model year before ordering. For WRX builds considering a front-mount intercooler (FMIC) upgrade, a TMIC splitter is not applicable. Professional installation recommended.
