GrimmSpeed Splitter for GrimmSpeed TMIC (15-21 Subaru WRX STi)

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.

Each of these splitters has been designed to make the best possible use of the air entering your scoop. We’ve opened up the bottom of the splitter to better fit your 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. Our engineers used 3D scanned CAD data from each vehicle along with the CAD data from our TMIC development to design a splitter that fits well and evenly distributes air across the entire core.

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 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 EPDM rubber bulb gasket, which installs with ease and will hold up very well to the harsh under-hood environment.
