    Throttle body hose install?

    2013 WRX, installing a aftermarket hose:

    Hi, I tried searching the web and the forums but cant seem to find anything on how to remove the TB hose form the manifold side since its hiding underneath all the other lines and tubings.
    Can someone suggest how I should go about getting to the clamp? I removed the TMIC, still cant figure it out.
    I can see it but just cant figure out how to reach the worm clamp's screw on the manifold side to get it out.

    I circled where I can see the other end where i can see the clamp.
    Any suggestions and pointers from those that have done it, that would be great. Thanks in advance.

    Wait, why are you removing the TB hose?

    There's already an aftermarket one installed, unless the clamp is loose.

    when you take off the intercooler just pull the hose off. The clamp shouldn't be that tight if it is just keep wiggling till it comes off

    When I removed my stock TB hose, I was able to stick a LONG flat head through the lines and tubings and loosened the clamp

    If the clamp has a bolt head in addition to the screwdriver slot (and it should) you can also set up a number of wiggle extensions on a ratchet. However if the IC is off you ought to have more room than it looks like right now.

    Basically, you remove the bolts that hold the plastic piece in the upper left of your picture. (It's a channel for electrical lines.) You can then push the cables and hoses out of the way, somewhat. (It's not elegant.) (I've done it (once) to replace the OEM IC with an aftermarket unit.

    I imagine that removing the IC will be necessary.

    thanks bobkn, that sounds like a good plan. I'll see if I can remove that plastic piece so I can move the lines a little.
