Why Fox Throttle Body?

spartanpride · Apr 9, 2011

What is the purpose of changing the stock 95 TB to a Fox TB? Also what's the advantage of installing a throttle body spacer?
Thanks

There is no advantage. I've had 2 foxbody Mustangs, and one of the biggest short comings of that car is the throttle body. The linkage is chinzy, and has a tendancy to fall off if it's been removed more than a few times. Which let's be honest, if you have a modded Mustang, that throttle body is going to come off more than a few times. Also, they have a tendancy to jamb. The SN throttle body is a huge improvement.

#16 towards the very bottom of the page, there's an article on swapping to a Fox throttle body. I still don't understand why you would want to do that...? That's why I'm asking, because like you said, it doesn't make sense to do this!

Ok... Here are my reasons

1. Able to run a cooled internal EGR
2. Cleans up engine bay
3. I can buy an accufab throttle body (doesent feel crappy at all.)
4. Some people say there is a HP gain but i havent seen that proven
5. Better throttle response has been reported by multiple users.
6. Able to clear Trickflow valve covers without running an intake manifold spacer.
7. The IAC even looks better.

also when people buy explorer motors their factory throttle body is larger then the stock sn95 so why not use it.

Im a fan:

There is an advantage to having the internal EGR, but it's not that big of a deal. I think the closest thing to a hp test I saw on here. I think Rio did a before and after dyno test with the fox throttle body. He actually lost 1 hp going to the fox throttle body. If you really want a big accufab throttle body, then it's probably necessary, but not too many people are making enough hp to require a big throttle body.

I agree, the only good reason to do it is to clean up the congestion in the engine bay area around the oil fill tube (plug wires, fuel lines, oil fill, throttle body, all in same area) or to be able to use parts that are much more available (bigger throttle bodies, blower discharge tubes, etc).

You can't run a strut tower brace without modification

Only reason people claim a better throttle response is because of the cam shape the cable rides in on the throttle body. Fox throttle is very touchy and when I got my '95 I found it easier to drive slower through parking lots, etc due to the pedal not being so touchy.

As far as ISC valve, they are swappable. A '94/5 will fit on a fox and vice versa. I personally don't like how the fox ISC wire plug faces down and touches the valve cover.

I have ran TrickFlow valve covers with my '94/5 cobra intake and no spacer and currently run fox valve covers with no problems at all.

I'm running a Holley Systemax with Trick Flow valve covers and the standard SN throttle body setup with no spacer. I think if I wanted to run an EGR again though, I would need a small spacer.

They only made that TB design for 2 years. I hate looking for 2 year specific parts. BTW i run a 90mm Accufab TB with an EGR delete plate. Also i feel the fox setup is alot more simple and mechanic friendly.
My first priority when i got my 95 was to clean up the cluster f#$% mess of an engine. It looks crammed and tossed together. I now have more engine bay room with my 351 based motor than i did with the 302.

Not that it matters buuuuut.....I can also remove both valve covers without touching my upper intake.

Is that a stovepipe connecting your throttle body to the MAF?

Okay thanks guys thats what I wanted to know!

Venom351R · Apr 11, 2011

It looks a lot better and it cleans up the engine bay quite well and I think there is a good bit of throttle response to be had, Im glad I had the swap done.

Because foxes are better.

Nope. Its actually thicker aluminum with welded seams in the elbow. I was having the problem of finding pipe to connect to a 90mm TB. I was wandering threw the local Pep Boys and found out that "Spectre" made all different aluminum pipes, sizes and elbows.

Ooops double post!!! Grrrr

revhead347 · Apr 13, 2011

Ok, that makes sense. If it was a stovepipe, I was going to give you the thumbs up.
