My AEM CAI keeps falling off, it seems like I can drive without it, but its pretty risky. The part thats falling off is the part attached to the throttle body. Has anyone had this problem? I've tightened everything but its come off twice now.

 

Thats weird. Try and use some big hose clamps.

 

make sure there is no grease, oil or anything that could cause it to be slippery

 

Nope never had that problem, so i guess you have something that causes it to be slippery or you do not have enough of the sleeve over the throttle body.
