intakes are not GT40 or P- only the heads. P heads have 4 bars on them vs. 3 for the regular explorer/gt40 heads and require special headers and different plugs. If I remember correctly they started making external EGR intakes m,id 97?. If your car has an EGR, then you want the intake with the EGR holes
And the ones without the EGR provisions also don't have the connection in the intake for the IAT sensor.

none of them due- you have to drill the boss on #5 runner. The difference is the earlier ones have a thicker boss to tap and drill. They also don't have the rear passenger pad tapped for hard coolant lines. Best to use the explorere hard coolant lines as they do not require tapping a return line into the lower intake.
Hmmm interesting. They guy I got my GT40 intake from claimed it came from a specific year (i dont remember) Explorer and therefore was ready to go without any modifications. It fit allowing me to retain everything else from my stock setup, IAT, EGR, coolant lines, everything. I'm going to ask him about it again. Just like you Mike, these things are a staple with him for many years.

What are you talking about tapping for a coolant line? I'm curious because I'm about to put an explorer intake on this weekend and I havent heard anything about that. Its an egr version if that makes a diffence..
I had an exploder intake from an earlier unit and the raised boss was there in no.5 runner, I just had to drill it. I've had both intakes with egr and without. I used the one with egr. I don't recall any changes to the coolant passages on any of them

Someone will have to back this up but if im not mistaken you can just put the intake on regardless if it has the egr provisions or not. I'm not 100% on that though.
I believe OneWheelPeel is correct that the ERG intake will work in a non ERG application. As for the TB spacer which holds the EGR, you can buy a non EGR TB spacer that will work with the setup.
What size TB are you planning on using? FYI, the stock opening on the GT40 upper is 68mm. So, 65mm TB and no porting is needed. However, it's pointless to upsize to a 70mm or larger TB unless you are going to get a spacer of matching size and also port the intake opening to match. Make sure you get a matching gasket too. On my son's car, a previous owner had used a smaller gasket which negated any gains from the 70mm TB which was on it.
I'm using a 65mm Explorer TB on my setup and it works great. Modifying it was needed to make it work in the Mustang application but it's not too difficult. If you want to try this option, let me know and I'll post some informative links.
There are Ford part numbers on the intake to correctly identify them.
On the lower intake, the P/N is right where the distributor would stab in. Only the last two digits here matters. -BA is the EGR intake, and -BB is the non-EGR version. Of course that is if you don't know how to visually distinguish between the two.

Ok well that's good then and I'm running a 70 mm TB it's what was on the car when I bought it on the stock 5.0 HO intake I'm porting the gt40 intake to match but would it be better to just go with the spacer?
Ok I know for sure that it's the EGR version and thank you for the information!
You need both. The spacer is an additional component. So, you need a 70mm non egr spacer , and you need to port the intake opening to at least 70mm. It's ok if the intake opening is slightly larger than 70mm. But you don't want it to be smaller. And, you need proper size gaskets that are 70mm opening at least, not smaller.
I'd go with these two.
SVE Mustang 70mm EGR Spacer Satin (86-93) 5.0L
UPR 5009 Mustang EGR Block Off Plate 5.0L 1986-1993
And no, if the intake opening is slightly larger than 70mm, it wont be a problem.

No more turbulent than air having to be pulled past a vane with a disc attached to it.
Just be sure there is no hard edge in the direction of air flow and your good.

I like these for egr delete, cleaner looking too.
