I know mustang 4.6 parts on T-Birds is a sticky subject. I was on hubcapplus.com and say a helix throttle body spacer listed available for what else than a mustang 4.6. Is helix any good? Will this or any other intake/TB/Spacer from a GT or a Crown Vic fit on a t-bird?

Why would that be? A majority of opinions I've heard... including a number from these forums have been the opposite.

Well, think about it ...any thing that installs easy and doesnt screw up performance normally , will sell very good with some reckless claims about performance increases. this has been true forever..... now lets ask how it works; does it do anything?Does it change airflow? does it alter the intake pulse to the intake runners significantly? Why hasn't the manufacturer incorporated it into the basic design?If every bolt on and toot& whistle, available for my car made the HP that the vendor claims the stupid thang would be putting out so much power that i would have to install a parachute on the back, go figure... In this case all youre doing is moveing the T/B a small amount farther away from the manifold intake/ gooseneck there is no real advantage in this ..... changeing intake runner size, length and shape can and does affect Hp/tq, but thats a pretty complicated area and you can usually get one only at the expense of the other unless you can enhance total flow significantly... changeing intake plenum size can affect power, but thats a pretty technical area too..... I think that the t/b spacer evolved from the 5.0 getting xtra power from a phenolic spacer between upper and lower intakes having the effect of keeping the upper isolated and cooler therefore not heating intake charge air as much.., in the case of a t/b spacer, there is no appreciable advantage, and I cant for the life of me see any physics or other weird science that would make this advantageous........It will probably fit,heck we can make almost anything fit, but why?

Yeah I've heard that spacers are only good for isolating heat like Leland said. But we already have a plastic lower intake so their would be no point to using one.

Actually, it started long before the 5.0 EFI, we used to use spacers on carbs to make up for running a single plane, short runner intake, to give some torque back by lengthening the runner track, and it worked. But in today's tuned EFI motors, it isn't good for anything, and noone I know of has seen any kind of gains from it, since our runner length is so long anyways.

Yeah, but remeber there is a fire danger involved here too, if you fail to remove the extra fuel.
But you shouldn't worry too much as those fuel saving devices will also create more horsepower , so you'll be able to out run any resultant fire.:D

welp the thing that a couple of ford dealer guys told me is that a tb spacer is like a barrel on a rifle. The swirl design inside the the spacer swirls the air ad in effect speeds up the air going into the manifold, in a more controlled manner. If it doesn't help it doesn't help. I appreciate the feedback anyway. :)

People say the same thing about the "Tornado". You will find that folks here "love" the Tornado.

swirling at the beginning of the intake does absolutely nothing since these engines have a swirl dam built into the combustion chamber of the heads, and who cares about swirling air, you want to swirl the air and fuel together, and there's obviously no fuel up there.

Ok,if that even happens with this item..what happens at the very first turn that the air takes inside of the manifold?? I think we all know that answer.

Yup, sold that one to a guy with one of those toronados on his intake, and marvel mystery oil in his crankcase, while he was putting 'garanteed magic stuff' in his gas tank. (quick sale)
