    My guess is it just isn't tightened down enough...only permanent solution is to tighten it down adequately? I dunno...I'm a silly 2005 owner.

    The whole thing is just poorly designed in my opinion. The glue holding the rubber gaskets (or sleeves) to the tube on either end apparently ends up breaking down. Once that happens the high flowing air essentially can get under the inside of the gasket and just pushes it out. The glue thing is what the tech told me at least when I asked for an explanation for this fairly prevalent problem in the GR's. The worm clamp seems to do it's job for a little but the gaskets are what seem to be the problem more than anything. They just find a way to help work the whole tube loose. Not to say that in this particular case it wasn't properly tightened, but having experienced it myself there's more than just a tight clamp that can make this tube fail. Some people have taken the gaskets completely off and used t-clamps to secure the hose which seems to be the best option other than aftermarket. The only problem with that, though, is that there's an increased possibility for denied warranty work if something would go wrong.

    I had an 04 STi once and, if I recall, those rubber gaskets didn't exist. Does your '05? Tried to find a picture of it and this is the best I could do...

    I saw your video and now I'm a little worried that my car is making the same noise. I thought it was because of cooler air, but not sure now. Did the dealer charge you a diagnostic fee to fix the problem?

    It was all covered under warranty.

    Not saying the tech was competent or not...

    FYI though, turbocharging is a method of supercharging a vehicle. It's just a specific type. Many older guys tend to say supercharger in place of a turbo... because a turbocharger is a specific type of supercharger.

    Glad they found the problem and that it is corrected minus the swirl marks =/

    I was going to say this^^ Same thing happened to mine the second day I had it in October 2011, pain in the butt to see and get to it to push it back on and tighten it.

    You saved me, if not for your thread, I wouldn't have gone to the dealer. Just got back, they are ordering a new hose for me. Although in the notes they said that the hose is coming apart, possibly due to overboosting.

    Yeah we definitely don't have any little rubber gaskets. We just have silicone couplers and hose clamps (that aren't even T-Clamps).

    Hey all,

    I had the same issue on my '12. Looking for others having the issue led me to this site and I signed up. Nice video, sounds almost as bad as mine did. I had the issue at 2500 miles.The part was replaced under warranty with new clamps. Sadly I have hit 4600 and guess what.... Here we go again. Glad to see others are also having the same issue. I'm a Toyota tech and we also own the Subaru dealer here as well and there is no change in the part yet. Was wondering if anyone was aware of an aftermarket solution? To the original poster.... Don't me mad at your dealer. Subarus break so infrequently I'm really not surprised it took a little poking to find it. Our dealership is only 2 years old now and our service manager is also the tech, service writer and parts guy. As the place grows we'll add on. Hoping to get moved over myself. Anyway he's like the Maytag repair man over at the Subaru building. I think if it wasn't for the used cars we sell he'd go insane with bordom. So if anyone has any ideas for replacing this part let me know.

    I just created a thread about possibly having a boost leak. I cant quite hear a sound like in your video, but I have my datalog graph which brought up my concern. SEE HERE

    I am also on a 2012 WRX with a AP Stage 1 tune.
    Is this similar to what you were seeing?
    Do you know if the tech at subaru did a boost leak test on your car prior to pulling the intercooler off?

    I didn't do data log (would have liked to but didn't have time)
    They knew the problems because there was a bulletin posted by Subaru about that exact issue, so my guess is they didn't do a boost leak test.
