ETS has designed a direct bolt on top mount intercooler for the 04-07 Subaru STI. This intercooler features a large 21x7x4 core with 31 charge rows! Most competing intercoolers have between 24-25 charge rows. By having 31 charge rows this intercooler has 62 heat transfer surfaces versus the competitions 48 heat transfer surfaces 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. The end tanks are hand built and hand ported for maximum flow, fit and finish. Unlike the competitors intercooler these 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.

Awesome TMIC
madcow6966768 5 years ago
I went out on a limb getting this intercooler because almost nobody I talked to has tried it. This is quite a massive intercooler. It weights substantially more than the stock sti one. The quality of the one I received is on par with the one in their video, which is pretty amazing. Fitment is good, everything bolts up the way it's supposed to. I didnt have to modify any of the A/C lines to get it to fit, which is a huge plus. Fitment with the stock STI air splitter is pretty much dead on as well. With the hood closed I can see that about 95% of the intercooler is inside the air splitter zone which is pretty amazing. Unfortunately I don't have back to back dyno tests done with this and the stock intercooler so I can't speak to it's performance vs that. But with a td06 20g I was coming in at around the mid 350's awhp on 91 octane with this intercooler. My only reservations about the ETS is the fact that all the thread holes go completely through to the inside of the intercooler. I'm not sure how they plan on you using their supplied studs when they thread all the way through without stopping. Also I would recommend using teflon on all bolts so as to minimize the chance of getting any boost leaks.

  • Q: which y pipe kit  Mlivingston1995 1 year ago


    Can't seem to find any pipe kit that fits this intercooler. Reuse oem?

    • A: Yes you will reuse OEM if you have the STI intercooler already. You will need the STI y-pipe.

  • Q: 04 STI TMIC  JeyMT 1 year ago


    I noticed in the photos, there are 2 pre-drilled holes for the PCV hardline. My 2004 STI has 3 bolts on the stock intercooler. Will the ETS come with 3 pre-drilled holes to mount the PCV line?

    • A: This will come with 2 holes to mount the PCV hardline like the OEM intercooler.

  • Q: Shroud  ShagginWagon410 4 years ago


    This fit on my 06 WRX and I'm trying to find a shroud that fits it better.

    • A: This intercooler is made specifically for STI models, but should fit your WRX if you get an STI Y pipe kit. The Grimmspeed or Process West splitters should work well with this TMIC, but we have not test fit them together.

  • Q: HP rating  maddx0513 4 years ago


    How much horsepower is this TMIC rated for?

    • A: There is not a hp rating for this TMIC, but the core should support approximately 450whp.
