Thanks for picking up our intercooler hose kit Joe! The link below is the kit in particular most applicable to the intercooler swap.

It may require some trimming to fit with the GD but should work out!

What particular quality issue did you guys have with our hoses? Just related to fitment or was it the hose construction you are concerned with?

Thanks

I've counted a 2015 last week. Same as 2014.

Further resurrecting this thread, because i just finished this project myself, here are my notes:

Installing a 2015 STi Intercooler in to my 2006 STi.

* bought the 2011 3rd intercooler bracket.
* bought the 2" 90-degree Mishimoto hose
* bought 2x Mishimoto clamps, sized 2.25"
* bought 3x Subaru intercooler bracket bolts [Note, I only ended up using ONE bolt]
* bought Grimmspeed gaskets for the y-pipe and BOV

took my sweet time wrapping the new GR/GV intercooler. If i didn't do this, this swap would have taken 2, maybe 3 hours, tops. I'm no expert mechanic either, but i'm a bit familiar with working on my car.

Except for the obvious of the installation of the intercooler to the car, here are my notes.

* the 3rd intercooler bracket (aka RH Intercooler stay 2) DON'T FIT in the 2006 GD STi. Maybe to those WRX owners out there, you'll need the STi RH intercooler stay 1 at the least! Where it bolts to the motor, the mount for the 2006 A/C lines interferes. Tried to squeeze it under, but then the A/C lines would rub on the mount. Ended up simply hacksawing the 3rd intercooler bracket, so it was "like an extension" of the original STi RH Intercooler stay 1

* on my 2006 STi, the Mishimoto 2" 90-degree hose fit perfectly fine. used their clamps too. When fitting it on the compressor outlet, it was easy to squeeze on. Though it appeared there was a bit "extra length", i just shoved it a little deeper on the compressor outlet. if buying Mishimoto clamps, be sure to buy the 2.25" ones, as that has enough clamp range to fit over a fitted 2" hose.

* after figuring out the bracket and the hose, it actually was about as easy as it gets. Perhaps the one part which involved a bit of flexing was lining up the intercooler bolts. Take your time and it will line up...there's quite a bit of movement available if you are patient.

I didn't want to mickey mouse it and have the intercooler held with only one side bolt and the throttle body hose, and using the 3rd intercooler bracket met my objectives.

For those who are really crafty, i suppose a metal plate with drilled holes would also work, but i liked the welded nut at the bottom of the OEM intercooler stay.

Now...on to the problem of the splitter. Open to hearing what others may have done.

Let me know if anyone wants pics of the 3rd intercooler bracket installed, or if you're interested in part numbers...

for me the fit is so tight that the brackets are really there just to hold it up. I dont even have it bolted down between the two brackets.

So there was only 1 person (I think) in this thread who installed this with a TD04.

Do we have confirmation that there is fitment issues with the 06 WRX and the TD04, or just the TD04 in general?

I have an 06 WRX and am looking at grabbing an 08+ TMIC to use with my TD04 as a supporting mod for a future turbo upgrade. It seems like the TMIC will generally fit but I understood there was some issues with the wastegate nipple hitting the intercooler.

Late to the party, but can confirm... I just installed mine and it hits on the TD04 wastegate.

Vlad, or all concerned for that matter, which splitter did you use with this intercooler?

I just used my GD splitter.

I talked to my tuner and after some back and forth mentioned that it wasnít worth fabbing up a custom one for me (cost vs benefit). I was still able to get good power out of it with the larger TMIC and my stock turbo, and Iíve since applied my funds towards other things...

SOmetimes, you have to think outside the box. The splitter, say a USDM Sti splitter, is easily modded with a pair of steel sheet scissors. It's also easily bent by hand with a set of pliers.
So you take the narrowest splitter, like for instance the WRX one, bolt it down, then mark it up.
Then start making cuts and bending it out. Then at the corners of the newly enlarged splitter, you seal it with epoxy putty.

The matter that is a bit more difficult is the splitter skirt.
The difficult part here is to find a long lasting adhesive. I did and it required two splitter skirts to make the enlarged one.
And yes, this was maybe 2009? so I forgot what I used, but it was sold by pep boys and was a two component adhesive.

Remember, the skirt has to sit on top of the lip of the intercooler, with a narrow rim protruding inside the frame of the intercooler, to touch the fins.

IN the end, you have an ugly but very functional splitter.

I added a sprayer nozzle as well.

I have pics from during my construction, I used a WRX splitter.

For the skirt that Vald is referring to i used garage door rubber sealer. Worked great for me and made the seal between tmic and splitter.
