After having the OEM duct come off repeatedly I finally pulled it all the way off instead of just refitting it and found the plastic air filter housing piece it connects to, bent out of shape. See photo below. The pic is of the air filter housing, not the air duct. The bottom portion where the clamp sits is bent up. I'm not sure of the cause of the deformation. It's not in an area where anything is pushing on it other than the clamp, and it shouldn't get too hot that it would deform.
Has anybody seen this? Is there a way to fix it other than replacement? I'm wondering if a hot air gun might be enough to warm it up and reshape it. I don't think this will work, as I can just picture it getting worse instead of better. Any other thoughts? ![]()

Jerry's Gaskets (I believe) can fix you up with a quality snorkel hose (Samco?) that will fix that. As also mentioned, you can do as I did and fabricate an aluminum insert that fits (snugly) inside the OEM snorkel tubing.

Kevin and Paul - I may not be understanding your responses, but my problem isn't the air duct - its the air intake (snorkel?) that it connects to. The Samco won't help, it will fit over this, but it won't be air tight unless the bottom of the snorkle it fits over is shaped correctly and not "caving in".

Replace the bottom housing.....same base as the standard vette.

l killed two birds with one stone by fabbing that insert and made so it extended inside that airbox flange - thus the flange is sandwitched between the aluminum (inner) sleeve and the snorkle and finally the steel strap. 6 years and counting...no problems (with a bit o' RTV as insurance against dirt slipping past).

I had the exact same problem, duct kept popping off and no amount of clamping would keep it on for long. I considered reinforcement, or possibly just using a small sheet metal screw, but in the end I ordered Jerry's brand new duct and a pair of clamps. Works perfectly, still in place exactly where it's supposed to, and I don't have to worry about it collapsing. It is a little long and required trimming above the a/c pulley, but that's all. It's considerably thicker than stock too, clearing the a/c pulley by a frog hair.

8CAM, what did you use to trim it? Scissors? I bought one from Jerry's as well with the new clamps and fit it last night, it also needed a little trim.
Did you make a "bump out" or a curved cut-out for where the A/C pulley is? I trimmed mine straight last night, but am wondering if I should put a little extra curve and trim more where the pulley is. The scissors left it not looking so neat, I think I need a sharper pair of heavy duty ones. I did use a heat gun on low setting for my original problem shown at the beginning of this thread and that helped a little, but I didn't want to put much warm air on it, as it will just weaken the plastic.
