Features & Product Details

RallySport Direct proudly carries performance products brought to you by our friends from the other side of the pond, Process West.

Here, you are looking at the Process West Hood Scoop Splitter. This splitter has been designed to take advantage of the increased surface coverage of a larger intercooler core. A poorly designed splitter will scatter the air flow to the engine bay, while the Process West unit will take the air coming from the hood scoop and direct the air to hit the face of the intercooler for improved cooling efficiency.


  • Durable aluminum construction
  • Powder-coated black finish
  • Controls and channels the air to hit the top of the intercooler
  • Helps take advantage of a larger intercooler
  • Forces air to flow through the whole intercooler
  • Comes provided with all Process West Top Mount Kits

    all the hopes and dreams for maximum airflow to top mount intercooler (especially for aps largest top mount intercooler) Not good for large intake manifold spacer gaskets by grimspeed (7mm) the 3mm worked perfect

    I have an APS top mount but it didn't come with a splitter, so finding one that would fit was a gamble. This one turned out to work nearly perfect, just had to trim the rubber weather stripping to fit it under the hood. Also, I have a replica STi scoop, so I'm not sure if it would work with the stock one, but if you're going with a big TMIC on a WRX, might as well get the big scoop. Another thing I love is that there are not one, bit THREE slots for the OEM intercooler spray nozzles. Time for a trip to Subaru. Overall I'm happy that this thing works as well as it does!

    • Q: Compatible Hood Scoop.  Gustavo Sucre1 year ago

      Is there a "compatible hood scoop" for this? I bought this part with the intercooler kit from you like a year ago, so far awesome mod, it allowed me to dial up the boost and keep my timing good... From the beginning the splitter started pushing my stock hood scoop outwards, which made me replace all plastic click-fittings with metal screws, since they broke... Now it's also beating this screws, creating some clearence between the scoop and the hood. Thanks in advance for your help.
    • Q: Process west splitter  Terrence5 years ago

      Will this 02-03 WRX splitter fit on a 04-05 STI hood scoop. I currently have a 03 STI hood scoop with the process west splitter but my friend wants to know if this specific splitter will fit on his 05 STI bonnet scoop
    • Q: VIS Carbon hood  Chrisrudnicki123681947 years ago

      I have a VIS Tracer Carbon hood on my 2003 wrx wagon and wanted to know if this would mount up to the hood no problem to fit into my stock tmic?

        A:  Unfortunately we cannot verify fitment with products that we do not sell. If your stock splitter fits the hood and lines up with the intercooler, then this one should also fit.

    • Q: Will it fit JDM 2002 STi  mustafa.alttahir430158 years ago

      Hi, I have a JDM 2002 STi and purchased a process west intercooler, wondering whether this scoop will work with 2002 STi (bugeye) bonnet scoop (rather than WRX bonnet scoop)?
      • 0 of 0 people found the following answer helpful

        A:  This splitter is designed specifically for the USDM WRX hood scoop and will not be a perfect fit for the JDM hood scoop. There will be a gap that will allow air to go around the intercooler rather than through it.

    • Q: will it fit   larrytang121558049 years ago

      I have a stock 2002 hood scoop and a turbo sx top mount. was wondering if this will fit
      • 0 of 0 people found the following answer helpful

        A:  This indeed will fit your stock 2002 hood scoop, we haven't gotten fitment confirmation of it with any intercooler cores other than the Process West so we are unsure how well it will work with the TurboXS unit.
