Good info and post evilClive!
I agree on the stainless (what I had), but i cannot find 60mm stainless tubing over here unfortunately and really wanted to open up the intake NOW!
Maybe some heat-wrap will keep things at a safe level a bit longer.
Alu is too well conducting imo and I cannot weld it together..hence the hard plastic. Most OEM manufactors also use some sort of plstic for intakes and what more under the hood afaik.
Tnx,
Walter
