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: 093073)
This will fit a Saabaru 7 years ago
5out of 5stars

After consulting Grimmspeed and install, the WRX '02-'03 splitter will fit the scoop for a '05-'06 Saab 9-2x Aero. The Saabaru scoop has a lower profile than many of the WRX/STI models, so splitter height was a worry. This one goes in without hassle.

  • Q: What spitter do I get???  YellowScooby7 years ago

    I currently use a hood scoop style like the 06-07 I believe (the one that the front of the nose sticks out a bit) I also will be getting a STI TMIC off a 07 STI. I've been trying to find forum to see if the JDM splitter is what I need or just a STI Splitter. I'm not sure of all the dimensions between all the splitter and the cooler mad the scoop? Please help me! Hope you understand the question....

      A:  Hello, This part is designed to work with the 02-03 wrx hood and scoop. If you're trying to use it on an 06-07 it will no correctly bolt up and will likely require modification. Mike
