I've got a storage tub (lol) for my air box with perspex on top and perspex siliconed into the box to reinforce it...
No melting and it's been in there for 2 months. Done a 3 hour road trip and heaps of city driving... No probs.
Air pickup is through reinforced rubber hose leading to the left front vent in the grille.
If your after pipe, go to your local truck exhaust manufacturer!!!
My truckie brother's suggestion, I thought he was nuts and it'd still cost me a fortune.
Got a stainless pipe mandrel bent for $25! Just had to cut it to the right length (was way longer than I needed).
Got some thermo wrap for it but it looks so much nicer without it.
I agree that plastic pipe would be much better insulation wise, I just don't trust plastic pipes in hose clamps in positions where there is stress put on it from engine movement. Last thing I want is a pipe to shatter and throw plastic through the inside of my engine (remember, it is in a hot environment and will become more brittle over time.)
I'll happily sacrifice the marginal difference in intake temperature for the peace of mind that I'm not gunna coat the inside of my engine in PVC...
