I just put your custom intake on my 89 Z and it works great. the only thing is that after a while, as the engine compartment heats up, the end of the filter with the clamp gets soft and the clamp slides off. the clamp is as tight as it will go and when it's at a cool temp and there's no way to rip the filter off so i know it's tight. It's when it gets hot that the clamp slides off. increasing the diameter of the pipe with a piece of rubber is what you said to Z24dogg and i'm gonna try that but how bout using some heat shielding under the filter?? could that lower the temp enough to keep the clamp on??
