Subaru STI TMIC Splitter - GrimmSpeed - 04-07. This direct-fit duct routes hood-scoop air across your top-mount intercooler for consistent, efficient cooling.

Designed by GrimmSpeed for the 2004-2007 STI, this splitter pairs best with GrimmSpeed TMICs and also fits the factory 04-07 STI unit. By directing airflow across the full core, it helps limit hot spots and supports stable charge temps under sustained boost. The model-specific shape focuses on coverage and fit so you can make better use of your hood scoop without adding complexity.
