GrimmSpeed 02-03 Subaru WRX Scoop TMIC Splitter - GRM093073

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. 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. This installation guide is currently being updated to reflect some small design changes. You'll notice that some kits will ship with a bulb style gasket. For these kits, start applying the gasket in the center of one of the four flanges and work your way around. The gasket will flex enough to follow around the bends. As you approach the end, you'll notice that you have a few extra inches of gasket depending on how tightly you've stretched it. Trim it to length at this time. If you'd like, you can make relief cuts in the bulb on the corners. A more detailed installation guide will be posted shortly. Please feel free to be in touch with questions.
