Is there any problems with bypassing the coolant around the egr plate or is it important

The coolant can help cool things down. EGR gasses are pretty hot.

Mine's been bypassed for a while. I bypassed it on a 2003 Silverado I used to have to keep the air cooler and since there was no EGR right there , I didn't have to worry about it getting too much hot air. I noticed that the throttle body stayed cooler without the coolant running through it. As far as my 'Stang, it's been bypassed since before I got it and so I couldn't tell ya any difference. I probably wouldn't recommend it because the throttle body could ice up and like Hissin said, the exhaust is pretty hot so the coolant will probably help cool it down a little.

It won't hurt or help anything. I bypassed them temporarily once but went back and hooked them up. If it's meant to be hooked up then why change it.

I was thinking about doing this as well actually, not using egr system and stopping the coolant from flowing through the spacer would actually drop my incoming air temp. depends on your app I guess.

You are going to be in for a slew of hassles with the computer once you start messing with the EGR. You will definitely be running permanent computer codes if you try and disconnect it.
When running with operating EGR you don't want to disconnect the coolant lines. The coolant, though seemingly very hot, is MUCH cooler than the exhaust gasses circulating around the EGR spacer.
It's your car so you can experiment if you want, but I would leave it alone if it were mine. I'm basing my info on personal experience with my 93, as well as the info found in the Mustang Perfomance Handbook by Mathis.

The EGR? They don't.


The coolant lines aren't used on the Cobra intake

The coolant lines are pointless. There is no way they do any measurable cooling.

On the other hand...the incoming air charge will not be inside the EGR spacer for long enough to warm up any measurable amount either...so it doesn't matter!

FWIW...mine are disconnected. So is the EGR system though

For something deemed so pointless, it's too bad Ford spent the money on it for all those cars.

Just because we don't feel a SOTP difference doesnt mean it is unnecessary. That's entirely different than removing or disconnecting it because we choose to.

Like the Cobra intake, the 94-95 EGR set-up is different (than a fox's) and magically, the coolant lines vanished. That indicates they are not for icing (a heat riser would be more effective for icing) but rather for the EGR.

They are more or less an engineering hold-over from early EFI days on the 5.0.

What do they do? Who the hell knows. They deleted them off the Cobra and later explorer intakes. I can't see any design difference that would cause such a thing. Ford is weird.

Still, i vote keep em. Too many people are delete happy and delete the wrong stuff on these motors. My #1 peeve is pointless EGR deletes (done incorrectly which is 99% of them)

I'm installing a Cobra intake so what do I do with the two hoses that went to the stock EGR spacer?

You could just loop the lines together.
Alternatively, you could find where each one branches off to go to the EGR (I can't remember myself) and if feasible, cap them right there. The former idea might be easiest.
