GrimmSpeed Top Mount Intercooler Splitter - 2004-08 Subaru Forester XT
OEM Splitter choking your TMIC? Fix that.
These have both been a long time in the making and as the popularity of GrimmSpeed intercooler offerings has skyrocketed, we've had a massive amount of demand for splitter options that maximize performance of our Top Mount Intercooler on the 04-08 FXT platform, with some users producing 600-700whp with them. These splitters are designed to seal perfectly with your GrimmSpeed TMIC, ensuring that the system works as efficiently as possible. With the dense cores that we use, forcing ambient air through the core with a properly fitting splitter is more important than ever and these splitters will allow you to do that with ease.
For FXT and STI owners that are currently using a GrimmSpeed TMIC, this is a must have.

Our cars, with even mild modification, create some serious heat. As the turbo compresses your intake air, it heats up and its not unusual to see air temperatures of over 400* F entering your intercooler. For that reason, youve 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 youre still using the OEM FXT size splitter, youre 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. Larger TMICs can increase your internal core volume by as much as 200% and youre going to need every bit of that additional ambient air to keep things cool.
DESIGN:
Each of these splitters has been designed to make the best possible use of the air entering your scoop and we offer a fitment for every 02-07 Impreza with a WRX or STI scoop. Weve opened up the bottom of the splitter to better fit your STI or big GrimmSpeed TMIC and weve redesigned the vanes that direct air from your scoop down to your intercooler. In addition, weve added features for up to three intercooler water sprayers to each splitter. Each splitter was designed in CAD and tested via flow simulation prior to production. Extra air diversion vanes were added to the splitters where there was space. Where there wasnt space (due to a smaller scoop), vanes were re-designed to more evenly distribute airflow.
MATERIALS:
Youll also find that the GrimmSpeed splitters are very lightweight. Weve tested some of the other guys splitters and have found that theyve chosen stainless steel instead of aluminum. The reason for this is likely as a band-aid, to ensure stiffness so that the splitter holds its shape. Instead of selecting a stiffer material, weve stiffened the design, which has allowed us to use 20 gauge 5052 aluminum and drop the weight of these splitters by 300% over the competition. Instead of welding the assemblies, weve opted to use flathead rivets. These offer the same mechanical joint but without stressing the material and because of that, you dont have to worry about breaking welds or your splitter cracking. With each splitter, well be including a length of a custom designed extrusion gasket, made from the same EPDM rubber as the OEM gasket, but better suited to fit our splitter. Pre-punched for split-shank rivets, you can be sure that youll get a great seal with no worries of failing adhesive or brittle rubber.
