Hey guys i just have a few questions, regarding the intake manifold. I need a new intake manifold for a 98 4.6l gt and was wondering if its a bad idea to buy a used "all plastic" one. Ive heard bad things about them, but money is tight right now and i can get one for $60 Canadian . Also if i should REALLY REALLY stay away from the all plastic what is an other option as far as used? Ive called a parts store where i usualy get really good deals and they can do $500 for new but thats a pretty chunk of change . Any ideas ?
