thats not really true. If you are bolting on new parts to your old sooted, coked up and clogged intake manifold there wont be any real benefit, but if you slap on a cleaned intake manifold (FCDP) that is basically "like new" you should notice a bit of a difference just because there is no restriction in the intake.From a performance standpoint there is no difference.
You can always take the intake to a machine shop and have it cleaned out. I agree that I wouldn't expect it to be too bad at 25k miles either.Sinister kit ordered..... The other products look like great products but I just dont see mine being coked up at all with 25000 miles. I also got a coolant filter as well. Im going for long term reliability next comes garret! Or 190s?
I strongly agree!If your going for reliability, I'd get a set of ARP studs before a turbo and/or injectors, just my opinion
you wouldnt believe how much soot is in one of those manifolds with the egr in place. I was amazed when I put in the intercooler @ 30K. one more vote for FCDP. a little more but it is worth it.Okay my truck has 25,000 miles on it. Is my intake manifold gonna look THAT bad? Would the sinister kit fit my needs as an all out performance and reliability standpoint? If it matters I have been running spartan tunes that keep my valve closed as well. So I cant even see it being that bad at all.
