hello i have a 95 with a 2000 model engine. the engine was pulled from a 98 and i put it in my 95. the valve cover has a sticker that says ford quality engine with the year 2000 written on it. anyway. i guess that means the heads are 2000 models to. well my 95 lower intake has a little bit different bolt pattern. it bolts up and i have been running the 95 intake but i also have the upper and lower intake that came with the engine, i am guessing they came from the 98. on one of the intakes it has 2 holes close to eachother and the same on the heads, but on the 95 intake it has the bolts further apart. this is confusing, i know it may be the other way around. i am not sure and i have the car parked somewhere else because i think v6 mustang should be discontinued.it is a piece of crap, i'd rather ride a bicycle to where i need to go before i drive this gas guzzling non running hunk. well is the 95 intake good enough for the 2000 engine or do i need to swap the intake. my car hesitates when the gas is revved fast from idle and this is the reason i ask. there is no vacuum leaks though and i guess that is all that matter on this intake huh. maybe i should'nt worry would a bad o2 sensor make the hesitation also. it is a single port intake.
