I feel your pain on the JLT CAI. A few weeks after I received mine, I went to the track. Ran a few times, then popped the hood...just happened to grab the CAI, and found I could actually twist the MAF housing inside the tube. When it cooled down, it stopped. So naturally, I thought the problem was the glue (or whatever that stuff is) was becoming overheated, and just allowing it to spin...then it would just seal it back up when the engine got cool.
I called Bamachips, always nice guys, and they had JLT send me a new tube. While uninstalling the old tube, I found my problem. The tube had actually cracked on the bottom where the tube meets the MAF housing...so when it got heated, I guess it expanded the whole damn tube, which allowed it to move freely. I haven't had any problems with my new one yet (knock on wood).
