It is a great installation video and a great product as well. Highly recommend doing this who ever won a WRX/STI. I am gonna do it by myself. Just wanna add a note on this thing: 1) Intercooler mount bolt torque specs are 11.8ft-lb 2) Intercooler hose warm clamps torque specs are 2.2ft-lb 3) Bypass Valve torque specs are 11.8ft-lb 4) There is two coolant line that is pre constructed with the AOS. I asked them about the order which line goes where (Since one goes to the Expansion Tank, one goes to the turbo outlet). They told me it does not matter. You can attach them in any order you want

Bout to do the install in a day or two. I have watched this video 3-4 times already, and will watch a few more times before doing the install. I have all tools ready to go, and am excited to get this on the car. My 2011 wrx had cylinder 4 compression issues, and I didn’t care for it as I should’ve, and definitely learned my lesson on what is needed for these cars to be healthy. I traded it in for a new 2020 STI that ive kept completely stock thus far. This video should be exactly what I need to understand the process more thoroughly. Thank you IAG, for providing this video. I understand most shops charge quite a bit for this so i decided to give it a go myself. I’ll let you guys know how it came out after I’ve finished the install. Next up after this is the cylinder 4 coolant mod, along with a Koyo aluminum radiator. Only then can I be comfortable doing performance upgrades down the road, as this is a daily driver that id like to keep healthy over its lifetime…

Alright guys, I’m taking a break. I’m at the point of reinstalling the intercooler, but having some issues with fitment. Should be able to get it on with some patience. I struggled to get the yfitting on to the block where the oil returns from the aos, that took me the longest to get right. Hard to see down there and I couldn’t get my throttle body to move quite as far to the side as they showed in video. The other parts that took the longest we’re getting the clamps all set right. Some of the steps took me longer than I was hoping, and I had more coolant leak than I would’ve liked. I’m sure I’ll get some smoke on start up due to that. I’ll come back after I get some rest and get the IC reinstalled. I hope to have the car running by this afternoon. I’m hoping it’s all solid and there’s no leaks on start up. I’ll have to add some coolant but that’s fine and was planned for.

Just used this video for my 2016 Sti. The install was a little different but pretty easy. I struggled to get turbo hose from Intercooler back on no matter what tool I used to get it over the bottom . I found that if you slightly change the angle of the hose downward it slides perfectly into the turbo without any tools and fits way better. I wanted to comment this for anyone who might run into the same issue. The version 3 is absolutely worth the money.

Use worm gear clamps where possible, particularly on the hose that drains coolant into the turbo feed. My provided clamp allowed it to leak. Also, if you are using a FMIC, just remove that bracket they tell you to feed the hose through the hole of. It is only used for supporting the TMIC. It will free up space and make getting the intercooler to turbo coupler on much easier.
@jasonhall3693 Жыл бұрын
This happened to me also. I had to run to wal mart to get clamps. I ended up using the one they provide it and a worm gear clamps. Just to make sure it wasn’t leaking because I was tired of taking off the TMIC.

Halfway through the install currently, will update when done! So far going smooth, biggest install for me ever so I’m taking my time and making sure it’s right! One note: when you go to put your Y splitter in consider re using the OEM hose the same size, it fits so much better and you won’t break the fitting or your hand trying to put it in, lol! There’s a video someone linked where the guy shows using the stock hose instead of the one provided by IAG!

I installed V3 on my STI so I kinda followed some part of this video but you have to see the other video from this guy BOOST AND SHUTTER.. he explains how to install on 2017 STI but the problem with THAT video is that he is installing a V2 instead of the V3.... once you get to the part of installing all hoses, you gotta SWITCH to this video. Im telling you this because I did mine like this and it was perfect install. If I had someone tell me this before I wouldn't have taken 5 hours to install mine.

Word of warning to those such as myself that live in cold climates. If you drive your car for extended periods (NOT stop and go) in extreme cold, the AOS lines WILL freeze. I'm currently thawing out my entire PCV and intake system. I want to emphasize that this is NOT, I repeat, NOT a problem with the AOS, it is an inherent issue with the location of the PCV and the intercooler on WRX's. The cold air blows through the intercooler, directly onto the PCV lines. Over time, this will cause the moisture (water) in your system to freeze and create crankcase pressure which will push oil into your intake, and possibly blow your dipstick out, which blows oil into the engine bay. One fix that I will try is to put cardboard over the intercooler to try to keep temps in the engine bay high enough to prevent freezing. This does not seem to be a problem with people that drive in stop-and-go conditions, it only really affects those that are driving on highways/interstates for prolonged periods.

So I just installed mine step by step, but i hear a hiss near the throttle body. Took the intercooler off again to check all my hoses and I can't find anything loose. When i give it a slight throttle the hiss stops but the car dies
@theiagchannel Жыл бұрын
We'd recommend getting a smoke test performed to locate the source of the leak. A few common places would be the intercooler couplers or the PCV hose under the throttlebody.

Is there an benefit connecting the 2 PCV hoses to the Blow By sensor white connectors versus connecting the 2 hoses directly to the block like IAG used to instruct to?
@satsun Жыл бұрын
If there is enough length on the hoses, you should be able to connect directly to the block as long as you jumper the PCV diag connectors to suppress the CEL. I've not seen the older instructions, but I'm guessing that these new instructions are more EPA friendly since they keep the diag connectors intact. I'm going to perform the install this weekend on a 2017 STI and I'm considering going straight to the block.
@trnql_noir Жыл бұрын
@@satsun Thanks for your input satsun. I ran them straight to the block with no issues using the jumper method. I am just curious if the Blow By sensors are important to the operation of the engine since not all systems are 100% efficient and some blow by will still make its way into the block. If you are still top mount intercooler that was the most annoying part of the install tbh. Other than that everything is straight forward. I suggest printing out the instructions in color, watch this video, and take your time. Good luck!
@satsun Жыл бұрын
@@trnql_noir Those connectors don't sense anything regarding the content of the lines, they're called 'PCV diagnosis connectors'. Their only purpose is to throw a CEL when the connection between the two parts is open. That's why it's easy to circumvent them. No operational impact by removing them. Glad you were able to run straight to the block. I'll do the same to eliminate those bulky connectors.
@trnql_noir Жыл бұрын
@@satsun I wonder why Subaru even implemented these sensors then. Emissions maybe? In my opinions its probably cleaner if you just keep the sensors connected so you do not have loose connectors dangling around. I have been debating whether I should go back and reinstall the OEM hose and sensors since I do not really see any downsides of keeping them. I thought maybe flow may be restricted but I really doubt it. What are your thoughts?
@satsun Жыл бұрын
@@trnql_noir I've already done some of the connectors, I used electrical tape to cover the exposed part of the connector so it doesn't get dirty and then zip-tied the connector to the wire harness or something nearby to keep it from hanging loose. They are either for emissions requirements or they're in place because certain PCV lines need to be modular for serviceability, so if part of the PCV system gets knocked loose then there's a system in place (CEL) to notify you of the problem.
