fast 90mm?

i'm doing a heads and cam swap and i was wondering if i should go with the ls6 intake or the fast 90mm set up. also what power gain would i get over the ls6 with the 90? it's for a A4

What kinda heads and cam? Sure, it has its benefits, but do you really want to spend 1100.00 more and be 10rwhp ahead of the LS6? (that was just a guess, so don't take my word on that.)

most people pick up 15-20 rwhp with heads cam cars,if you remove the MAF sensor at the same time and get a sd tune you can pick up another 10-15.Thats what seperates the people who gain 20 with a fast to the people who gain 30-35.if you cant remove your mass air,then IMO its not worth it.
