Im getting ready to do a pre 93 intake swap on my 95 gts and was wondering what are the coolant lines on the egr spacer for? do they have anything to do with the functionalility of the egr or are they just to heat up /cool the intake there?
Function of coolant lines to egr spacer?

The coolant lines carry the engine coolant that cools the comparitively hot recirculated exhaust gases. Leave them hooked up if you have the gases flowing through it. This has been asked several times, if you do a thread search for it you can find more information. But, the general opinion is that you should not stop that flow of coolant.
ok, yeah im sure its been covered a thousand times before, im just new to the foxbody stuff, the 94-95's have a completely different setup, same block, but alot of stuff is different. ok, well i have the egr blocked off at the heads, so i wont be having the gases flowing up through there. and i dont have provisions on my coolant transfer tube for those lines anyway since its a 95 gt, so as long as there is no function except to cool, then i wont bother to try and connect them.

Yea, that should be fine then, I'm not an expert on 94-later stangs but the EGR spacer should be the same setup and function as mine. By the way,

I had to jerk off the cable to get it to stop.

I dont know about the SN-95 intakes but the Fox intakes have the EGR gasses flowing through the intake through a hole in between the runners. the gasses are not flowed through the holes in the back of the heads, well they are but not the EGR gasses. If i were you i would leave the EGR hooked up, the computer will pull fuel and add timing, because it can not sense the gasses in the intake, it just thinks they are there. If you dont hook it up without properly deleting the EGR via Tweecer or chip then this could lead to detonation or (pinging) and worse gas mileage. I wouldnt delete it do a search and read what everyone says about it. I would also hook the coolant lines up because like said before they cool the hot ass exhaust gasses. Just my .02

the 94-95's use an ugly external egr that is a pain in the as& with any kind of header or tb mods. i like the idea of an internal egr. if i do decide to delete it (im not sure yet) i will have a chip burnt which i was planning on doing anyway to eliminate any problems. so far i havent had any detonation, probably due to my afr 165 aluminum heads dissipating the heat better. but keeping the internal egr is an option, i will have to unplug the egr passages though which requires removing the lower intake again to remove the block off plates, which isnt hard, just time consuming.
