Description

GrimmSpeed 15+ Subaru STI (fits GS TMIC) TMIC Splitter

MIA's Description

The GrimmSpeed Intercooler Splitter is designed to mount beneath the factory hood scoop and direct ram air over the GrimmSpeed TMIC surface for 2015-2021 Subaru WRX and STI models. Without a splitter, much of the available ram air misses the intercooler core entirely, representing wasted cooling potential.
