did a search on this topic because i really didn't want to ask such a dumb question, but i came up with nada... i'm doing my h/c/i swap this weekend, and i realized i never bought the "phenolic" spacer for the intake manifold that was recommended... is the thing BS or what? does it really create a colder intake charge or is the difference negligible? will it affect my hood clearance or valve cover clearance? any help is appreciated, thanks
