GrimmSpeed Top Mount Intercooler Splitter - 02-07 WRX/STI

Tired of popping your hood only to have that ugly OEM Splitter remind you of how badly it deprives your fancy TMIC of the cool, ambient air that it requires? Perhaps you’ve upgraded to an STI scoop and want to really make use of that extra air? Maybe you’ve already got an STI splitter but want to squeeze every ounce of performance out of your top mount. After frustrations with this and more, the GrimmSpeed team has the real solution. Well, five real solutions. Introducing, the GrimmSpeed TMIC Splitter lineup.

Our cars, with even mild modification, create some serious heat. As the turbo compresses your intake air, it heats up and it’s not unusual to see air temperatures of over 400°F entering your intercooler. For that reason, you’ve probably upgraded to a larger, more capable top mount. That intercooler uses ambient air flowing over your hood and through your scoop to cool the hot compressed air and if you’re still using the OEM WRX size splitter, you’re not getting the most out of your TMIC. The GrimmSpeed line of splitters increases the size of the opening by 70% to your larger TMIC. STI or aftermarket TMICs can increase your internal core volume by as much as 200% and you’re going to need every bit of that additional ambient air to keep things cool.
