GrimmSpeed was founded in 2006 to provide customers with innovative and highly engineered aftermarket products. On a more personal level, we are a group car enthusiasts who are working our passions in the lovely city of Minneapolis, Minnesota. Our bread and butter started out anything Subaru. However, after growing our team and engineering expertise, we started developing products for Mitsubishi, Ford, MazdaSpeed, and Hyundai markets. We are a true garage start-up (single stall townhouse garage in Maplewood, Minnesota) and we've been lucky enough over the years to be able to turn it into exactly the business we had dreamed....actually, much more. We have a wide breadth of product offerings including; intercoolers, exhausts, intakes, gaskets, engine pulleys, phenolic spacers, boost controllers, and many more.

OEM Splitter choking your TMIC? Fix that.

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. Larger 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.

 

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. We’ve opened up the bottom of the splitter to better fit your STI or big GrimmSpeed TMIC and we’ve redesigned the vanes that direct air from your scoop down to your intercooler. In addition, we’ve 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 wasn’t space (due to a smaller scoop), vanes were re-designed to more evenly distribute airflow.

 

Materials

You’ll also find that the GrimmSpeed splitters are very lightweight. We’ve tested some of ‘the other guys’ splitters and have found that they’ve 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, we’ve 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, we’ve opted to use flathead rivets. These offer the same mechanical joint but without stressing the material and because of that, you don’t have to worry about breaking welds or your splitter cracking. With each splitter, we’ll 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 you’ll get a great seal with no worries of failing adhesive or brittle rubber.
