well this may be a dumb question, but id rather ask then be stuck high and dry.

im going to grab a TB and plenum setup used that is already bolted together which includes the EGR and IAC along with barb fittings and they are already bolted together.

my guestion is, every TB/plenum i have removed has had a gasket. But i remember seeing only a ruber o-ring type deal on the top of the intake manifolds...(04 GT)

do i need any gaskets for this install? one from plenum to manifold? other than prob egr and IAC gasket if im using mine and take ones off of TB/plenum

sorry if this is really dumb but just want to make sure.

thanks for any help

I'm pretty sure that rubber o-ring type seal on the manifold that joins the manifold to the plenum is sufficient. Thats what I did and everyone else I know and I've had no problems so far

+1...same here.

cool, thanks alot guys.

might as well ask if the stock rubber intake tube can slide over the 75mm TB, i dont have the setup yet but wanted to know some things before i got into it

StriderTacticaL

I know it will slip over a 70mm with no real problems but going over a 75mm is a really tight fit. I've heard of some people cutting a split at the end of the tube so you can pull it over but I don't think that is a good idea since it could tear all the way down.

My idea would be to put the end of the stock intake tube into some really hot water for a while and then see if you can stretch it over.

thanks alot Strider, that mixed with some WD40 im sure would work.


i may just use the plenum for now since the 75 i have heard is a little overkill for stock motor and that it can flow more than enough CFM.

+1 I used a heat gun when me and my friend put the a 75 on his. Just heated it up enough so it was flexible enough to stretch over. Worked perfectly

mrtstang

It was a little snug, but it fit over my 75mm just fine without having to heat it up or anything.

Cool thanks alot guys. Just wondering if it would be even close to fitting.

In the end i think im goin to have some 3" exhaust pipe bent up for am intake tube. Yes it will be metal and hope it doesnt heat soak THAT bad. At least $100 or more for a CAI doesnt appeal to me. I already have a Densecharger fender CAI, but was going to replace the ribber rubber tube.

i know it wont do me that much good over stock, but my rubber one has diry and grime that doesnnt clean too easily, plus i can put a custom paintjob on the new pipe.

actually come to think of it, ill just make it out of fiberglass, that way the fitment will be perfect...not to say that anything like C&L or JLT are not good fits.... they just cost too much
