91PA, the intake manifolds aren't ABS. They're a glass-impregnated thermoplastic. In other words, plastic and FIBERGLASS (which is a known insulator) molded together.
ABS has known heat-retention properties.
I suggest we all go back and read the topic authors original post and try to answer him in the best manner possible.
