Tips on how to keep a CAI from falling off

Does anyone have any tips on how to keep a "DIY CAI" from falling off? I run a 3" coupler from the TB to a 3" 45* pvc pipe to the MAF and then a specter cone and it always falls apart between the coupler and the pvc pipe. Could I just use like glue or something to keep it together since the clamp isn't working or can someone else give me a new idea? Thanks in advance, Mike
 


Do your clamps hit the stop points? Never heard of a properly clamped intake coming apart. heck..mine is only clamped and it holds itself up.
 
Well I clamped it down as much as possible, even used a drill on the highest setting to make sure and it still comes apart on me after about a week to two weeks. You guys are just running the clamps from like home depot or lowes correct?
 
Yes.

Maybe take pictures and post them...

Because this makes no sense if yours doesn't work out of the other hundred+ that do.

The heat from my engine caused my pvc pipe to get soft/shrink and my filter would fall off. Solved it by getting a metal pipe.

So this is what it looks like basically and for some odd reason it just doesn't want to stay together. Sorry if the pics don't help to much they were from when I put it on
 


mine has fallen off a few times too, every time the clamps are loose. even the filter has been found loose from the pvc, but that has not fallen off. oddly enough, the clamp on the TB never comes loose. maybe a dab of locktite would keep it tight? may have to try that one myself.

the last time i jammed the pvc tube in as far as i could into the coupler, and clamped the crap out of it. so far so good. no zip ties holding mine either.
 
It looks as though the PVC elbow isn't very far into the rubber coupler. The super smooth surface of the elbow probably reduces the grip between it and the coupler. I'm not sure that the sizes are correct either.

I would ditch that setup and buy a 3.5" to 4.0" coupler, a 45* 16 gauge aluminum tube elbow, and a 9" long filter with 4" I.D.
 


I kinda figured it was just a bad clamp, now would it be best to just go to like autozone and get a exhaust clamp and use that or is that way to much overkill? The pvc is pushed in as far as it will go also
