Best TMIC on the market! Extreme Turbo Systems has designed a direct bolt on top mount intercooler for the 08-21 Subaru STI. This intercooler features a large 21x7x4 core with 33 charge rows! Most competitor intercoolers have between 24-25 charge rows. By having 33 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 2008+ 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 runs 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.
This intercooler is NOT compatible with the 08-14 WRX

Customer Reviews
ETS were great from start to finish and the tmic was stunning and superb quality i can praise them enough if u want top quality then these guys are the ones to go to well done guys
It was a fast and easy experience! Intercooler fits great and shipping was quick
Great
So first I’d like to say thank you to Ryan over at ETS, for helping me sort out some technical difficulties I was having with fitment. This is a beefy tmic, it’s solid with very nice welds, and a huge upgrade over OEM. Already seeing a difference in temps and feeling it with out a tune excited to see how she feels once we get her dialed in. Thank you Ryan and all the guys over at ETS for your help and for putting out top shelf parts.
Looking good! Thanks for the feedback, we appreciate it!

QUESTIONS & ANSWERS
Ask a Question-
Do you guys by chance make any tmic for wrx?
We do not offer a TMIC for the 08-14 WRX and have no plans to introduce one at this time. We do make a FMIC that is compatible with the WRX turbo location and intake manifold, however.
-
does this fit a subaru 2009 wrx its not an sti
This DOES NOT fit the 08-14 WRX, it is only compatible with the STI.
-
I already purchased this awesome TMIC for my 2011 STI. Has anyone made a hood scoop duct/splitter to fit this TMIC?
We designed our top mount to work perfect with the factory scoop/duct. To be honest, I'm not sure if anyone makes a better scoop than the OEM scoop.
-
does this fit with ets rotated kit?
The TMIC does not fit with our rotated kit. It requires a front mount intercooler.
-
Will the stock or stock replacement bpv bolt on
Yes it will
-
Does this come with a coupler?
This includes the coupler to the throttle body.
-
Do you guys offer the 21" x 7" x 4" intercooler core size? I noticed Rallysport is selling it but only the Silver core. I am assuming the 2 inches make a difference in better cooling, new to this. But I am looking to purchase the red with stencil. Do you guys also offer military discount ? Thanks for your time.
Core density plays a much bigger factor then the size of the core. This is good for cars under 500whp.

Is the standard Sliver Core also anodized?
No it is not. It is raw aluminum
-
Does this require a tune as a standalone upgrade or can i just do a one for one swap with the stock TMIC for the ETS TMIC and be good to go without a tune?
You can just swap it out without a tune but a tune is always recommended.
-
What is the size diference between the STI +15 stock intercooler vs. this one? How much in %?
Our TMIC is over an inch thicker, our finpack is way denser and we split our finpacks 3 times. This allows for way more cooling surface area.
-
What is the difference between this 08+ STi TMIC and the 04-07 STi TMIC that you offer?
The 04-07 TMIC is a smaller core and uses different mounting locations.
-
How much hp is this intercooler rated for?
We have some cutomers running around 550WHP but we typically recommend the TMIC for cars 500WHP and under.
-
Will this work on a 15+ WRX?
No, this does not fit the WRX model. It only works on the STI.
-
Will this intercooler fit a 2008-2014 WRX?
No, this does not fit the WRX model. It only works on the STI.
-
Does this fit on the 2021 STI and does it require a tune?
This is compatible with the 2021 STI and does not require a tune for proper vehicle operation. ETS always recommends a custom protune for the optimal performance, however!
-
how much is the HP capacity of this top mount intercooler?
Flow rate is capable of moving a lot of air, but the thermal properties will limit the max horsepower to about 450-500hp safely.
-
Hi I have a 2013 WRX STI with a 93 tune for my car with the stock intercooler if I where to put a top mount ets intercooler would I need to retune the car again?
A tune is not required to run this intercooler, but you won't see the full benefit of the part without re-tuning to take advantage of the increased cooling capabilities.
