really why do you think GM uses the same material to make their intake manifolds ABS plastic is less to prone to heat soak especially the pipe i recomended becauce its thick walled and also has air constatly pulling through it and ive had PVC pipe since like 2005 ive actually tested this compared to aluminum and flex pipe designs and PVC out flows and has lower intake temps on a consistent basis no th eplastic wont warp no it wont emit any toxic gas and no it wont crack when its cold or hot

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.

posted that twice on accident look up the thermal properties on both materials i know mani;* arent ABS thats my fault but for real let people make up their own minds about this and for the record there are similar cost effective solutions to the intense FWI case closed

Intake manifolds are NOT ABS. Read what I posted above. Please get back on topic or quit posting in this topic.

You've stated your case, and we'll let the members decide by the information posted and their own research whether or not they want to use ABS for their intakes.

thank you
