2000 Mustang GT 4.6L SOHC. the part that the thermostat sits in is cracked i've looked around and searched this site and others, but no one mentions if the coolant crossover can be replaced by itself or if i have to replace the whole intake manifold. i've seen ones with an aluminum crossover (which all should be) but mine is made of plastic. does anyone know if i can replace just the crossover or do i have to replace the whole manifold? thanks.

i dont recommend buying it off anywhere but ebay.
you can find a very good used one for under $100.
unless you want a brand new one. then go to american muscle or something like that.
but yes, you have to replace the whole manifold. Thank Ford for that one.

yea i found the ebay intakes, they seem to be decent pieces with the aluminum crossover's. but are they a performance piece or is thier a performance manifold that i can get and where? im not familiar with mustangs so im having a hard time finding this stuff out, and if im going to be changing a manifold i might as well get a better performing one, even if it costs a little more that the $200 ebay ones. and one more thing i dont understand the difference between the the "PI" performanc improvement heads, is that what came on the 2000 GT's? im unsure of which manifold to get PI or NON-PI, thanks for you guys help.

You need a PI manifold. I got sick of that freakin thing being broken and didn't want it to come back EVER so I bought a full aluminum intake. Yeah it cost $700 but I can not worry about that anymore plus i got a little gain in performance. Dyno numbers coming by Saturday.

I also put on a full aluminum intake and I have my old one I will sell if you want it. If I was you though I would just buy the aluminum one.

quickstyle

does it have the aluminum crossover?

ratherBracin

Yes it is off of my 2002. I wanted to change intakes before I put a blower on.

i got to go to work so i will get back to you later, how much do you want for it? and to which manifold were you refering to earlier that is all aluminum, the only one i can find is the trickflow track heat one.
