Product Details

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 400F 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 not using a proper splitter, you’re not getting the most out of your TMIC. The GrimmSpeed line of splitters increases the size of the opening to perfectly fit your GrimmSpeed TMIC, which can increase your internal core volume by as much as 200%. You’re going to need every bit of that additional ambient air to keep things cool.

• Laser Cut 5052 Aluminum Construction - Durable and lightweight construction
• Texture Black Powdercoat - Protects the assembly and gives a nice finished look
• Rubber Bulb Gasket - Included with each kit for a perfect seal

Design

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.

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 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.
