OK i cracked my intake manifold on my 99 gt and since it was under warranty i took it into the local ford dealership. and they put the ford racing pi intake on my car

now i was under the impression that i could not put this intake manifold on my car with out pi heads. all i have is stock heads. now when i am in 3rd or 4th and i step on thegas the car sputters. is it true that i need pi heads or a computer retune? i asked the mechanic who put it on and he said i did not know what i was talking about and the sputtering has nothing to do with the intake and there must be something else wrong. i say he does not know what he is talking about cause it never sputtered like that before and had lots of power. now it struggles to pick up speed. any expert advice would be appreciated. thanks

 

arent 99-04 already pi motors?

 

01-04 are pi motors, I THINK, that link says its current prod on 01-04, dont know why it would not include the 99 and 2000, unless they have different heads. WEIRD

 

99-04's are PI motors...so that intake should fit fine...hmm that is wierd that it doesnt mention your year, but yes it is just a direct replacement

it fit ok. just the car is working like a$$. and it never did it before. its like the a/f ratio is off or something.

 

thought so never heard of a npi new edge.

 

so if I'm understanding this right my 99 has the pi heads?

 

yes

 

Yes your 99 has PI heads. All 2 valves from 99-04 come with PI heads.

 

ok cool. now all i have to do is find out why the ole girls i sputtering.i just filled it up, maybe it was bad cheveron gas. lol. i did put the 94 oct in it.
does the computer need to be retuned or anything?
