Best TMIC on the market! Extreme Turbo Systems has designed a direct bolt on top mount intercooler for the 04-07 Subaru STI. This intercooler features a large 19x7x4 core with 31 charge rows! Most competitor intercoolers have between 24-25 charge rows. By having 31 charge rows our intercooler has 62 heat transfers vs our competitors 48 heat transfer place which results in a greater heat transfer area. This core is designed specifically for the 2004-2007 Subaru STI this is not an off the shelf core. Unlike our competitor's intercooler, we require no modifications to the a/c line that run behind the intercooler. The intercooler also uses studs to mount the blow off valve instead of bolts, this means no stripping out the holes when over tightened. This intercooler has been designed for maximum performance.


  • 19x7x4 large intercooler core

  • Clears the A/C line.
  • 31 Charge Rows / 62 Heat Transfer Plates (Competitors: 24 Charge Rows / 48 Heat Transfer Plates)

Ask a Question
  • How's does the Sti splitter line up with this TMIC? Is the grimmspeed splitter fit comparable to the OEM?

    We designed our intercooler to be a direct repalcement to the factory intercooler.  This means any shroud that works with the factory intercooler should work with our top mount intercooler.

  • Hi does the stencil come printed on the intercooler if you choose the stencil option or does it come separate and we put it on ourselves?

    The logo comes painted on the intercooler if you choose the stencil option.

  • Hello does this utilize the stock STI Y pipe?

    Yes it does

  • Hi, would it be possible to get an IAT bung pre-installed? Kind regards, Manfred

    Place it in your order notes and we will see what we can do.

  • Is the red anodizing the same colour as the red intake manifold in an sti?

    It is a bit darker and has more shine to it than the red powder coating.

  • Will this fit a 2005 wrx?

    It requires STI Y-Pipe and Mounting brackets but yes it can be made to fit.

  • What is this intercooler rated for?

    They are good for about 450whp-500whp, but due to being a top mount they do suffer from heat soak a tad quicker then an FMIC would.
