Features & Product Details

This is the Grimmspeed Top Mount Intercooler Hood Scoop Splitter. The main intention of this component is to provide better air surface coverage to the top mount intercooler. Although the factory splitter is functional, there will always be room for improvement and Grimmspeed knows how to make the most out of your factory top mount intercooler. 

If you purchased a vehicle that came with modifications, or if you plan on going down that path of modification, things like an upgraded exhaust, fuel injectors, larger turbo, basically anything else will push more heat through your top mount intercooler and you will experience heat soak beyond recovery. For example, if it's in the middle of summer and you're at the drag strip, it is not unusual to see air temperatures in excess of 400° entering your intercooler. For these reasons, people will typically upgrade to a larger top mount intercooler. But that's not always the right answer. Because if you're still employing the factory splitter setup then you are not getting optimal surface coverage.

Grimmspeed designed their splitter to increased the size of the opening by 70% which will work with an STI intercooler or a larger aftermarket top mount intercooler. Other features include redesigned vanes that direct air from your scoop down to the intercooler. Additionally, they have added features which include extra provisions that will allow up to 3 intercooler water sprayers to each splitter. These splitters have been CAD designed and have been tested with flow simulation prior to production. Extra air diversion vanes were added to the splitters where there was space to help evenly distribute the airflow. 

Weight was also the focus on the Grimmspeed Splitter. Rather than stainless steel, Grimmspeed opted for 20 gauge 5052 aluminum materials which drops the weight by 300% when compared to other aftermarket splitters. Flathead rivets were employed to keep the splitter together which offer the same joint stability without the need for welding which you risk breaking welds or cracking. Each splitter will come with a custom designed extrusion gasket which has been made with the same EPDM rubber materials as the OEM gasket for quality assurance. The splitter will also come pre-punched for split-shanked rivets and then molded with a 15° flare to provide a great seal without the worry of failing adhesive or worn rubber. 

This splitter has been powder-coated a nice black finish for extra protection against rust and corrosion and will come ready for the installation.

GrimmSpeed Hood Scoop Splitter ( Part Number: 093077)
Great design and quality 2 years ago
5out of 5stars

I installed a Grimmspeed TMIC and figured I should compliment it with the GS hood scoop splitter. Comparing the two, OEM vs GS, you can see the improvements. But I would say for STi owners, if you're sticking with the OEM sti TMIC, I wouldnt bother upgrading the splitter. I can see this part being beneficial to those living in warmer climates that need all the help they can get with heat exchange. I feel it's a little unnecessary for my daily commute, but once I start tracking my car, I'll be glad I have it.

Amazing quality to be expected of Grimmspeed. Durable construction. Perfect fit. IMO this part really is necessary when upgrading your top mount intercooler. Only complaint is the high price for what it really is but gotta pay to play right?

      A:  Fits the Performance Mishi TMIC on my 07 WRX. The baffle flanges can be bent slightly to create maximum coverage over the core. This is a very well made shroud that bolts right up in minutes. Go for it!

      A:  If your 03 WRX is using the JDM 02-03 STi hood scoop, then the splitter you will want to run is part number 093074. Hope that helps! Andy

  • Q: I/C Spray Retention  Brock Samson6 years ago

    I have an 07 STi which has the Intercooler Spray line that runs to the OEM splitter. Will this splitter let me retain that function?

    • 0 of 0 people found the following answer helpful

      A:  This splitter was designed to be used with the GrimmSpeed TMIC. The STi intercooler core is similar in length and width, so the splitter should work well for you. -Andy
