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 200% 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 Splitter for my GC8 4 years ago
5out of 5stars

This product is very well constructed, and was the closest thing to the OEM hood scoop on a 2000 GC. The bolt holes don't line up of course so I had to make significant modifications which I knew going in. I'm pairing this with my Grimmspeed Top Mount Intercooler and sofar the fitment is working great for directing air into that guy.

Must have for a larger intercooler 6 years ago
5out of 5stars

Matched this up with a JDM STi scoop (2002 bugeye) and Grimmspeed TMIC. Works as it should, fitment is snug, much better than the stock shroud at dispersing air over the entire intercooler.

Looks great, works better than a stock WRX splitter 7 years ago
4out of 5stars

I like the GS splitter, but have doubts about the longevity of the shrouding material. It's flimsy and I will be amazed if it lasts through Oklahoma summer heat. That said, so far it's doing a great job piping air down onto my STi IC. I also have the JDM scoop, and the three items together (Scoop, splitter, IC) make for some real butt-dyno gains.

QUESTIONS & ANSWERS

  • Q: Is this the scoop for my 2002 WRX?  Kellen Morse2 months ago

    Hello, I see that fitment is noted for the JDM STI scoop but is this the splitter I want if I were running a Seibon hood scoop?
  • Q: 2007 forester sti  Nickersoncj006 months ago

      A:  Yeah I would imagine this would be your best bet to get better coverage, now with that said, of course we cannot guarantee fitment, but it should work :)

  • Q: Will this fit a 4" scoop?  Gerken10 months ago

    Hello, will this product fit an aftermarket scoop advertised as 4" tall opposed to the jdm sti scoop measured at 3" tall? Thanks. 03 bugeye wagon.

      A:  We cannot confirm if they will work with other aftermarket hood scoop. If your 4" hood scoop is a direct replacement for the OEM hood scoop, then it is possible that their splitter can work with that scoop.

  • Q: STI I/C water spray  My OEM splitter that holds the sprayer line12 months ago

    Will this splitter hold the factory STI I/C water spray ? (I have STI 2002 bugeye with original hood scoop and aftermarket intercooler) Thanks:]
  • Q: 2002 WRX with EJ25 swap  acastro166973532 years ago

    I was planning on throwing this along with the grimmspeed TMIC on a 2.5 swapped WRX which has the JDM scoop. I was wondering if this was the correct combination of parts and if the TMIC lines up the same?
