Thought I'd provide a few pictures and general factoids about the Windsor factory intake manifolds as the topic comes up often enough.
For instance, all these factory intakes have longer runners which improves the lower ~ mid range torque. On the other hand, aftermarket intakes generally feature shorter runners which can assist with developing power up higher in the rpm range. HO average flow approx 140cfm ports are inline OEM fitment to EB, ED, EF, EL  Explorer average flow approx 170cfm ports are staggered - lower intake is same for Explorer, GT40 & Cobra. OEM fitment to EL XR8 (later series) , FBT, AU XR8  GT40 ( Tubular ) average flow approx 195cfm ports are staggered - lower intake is same for Explorer, GT40 & Cobra. OEM fitment to EB GT, EL GT  Cobra average flow approx 200cfm ports are staggered - lower intake is same for Explorer, GT40 & Cobra. OEM fitment to ED Sprint

Probably worth mentioning that Explorer lowers cast from late 1997 (ie all Aussie Explorer intakes fitted to V8 AU Falcons) did not have the IAT sensor mounting hole or even the undrilled mounting boss, so any upgrade from an HO intake to an "Aussie" Explorer intake needs to consider this
The EL2 XR8 seemed to get the "early Explorer" lower intake that still had the IAT sensor in the standard location. Whereas the Cobra lower carried the standard IAT sensor location on to the present day. Strange that Ford would have two variants of the same lower. Usually they just use the same lower and don't drill & tap eg. 1994-95 HO Mustang uses an HO lower with undrilled IAT sensor mounting boss. And the AU3 XR8 had a match ported Explorer, and flowed a little more. Gasket matching was done on the lower (both ends of the runners) and the upper (runner end), with the upper also match ported to accept a 70mm TB.

This is very helpfull, thanks Vic.
Pardon my ignorance, but I have the $hitty H.O manifold on my Ef xr8 and am looking to upgrade to most likely the Explorer, and have pretty much given up on any chance of coming across the convenient El series 2 manifold with the sensor and all. So I'm wondering if you guys could give me a rough sort of figure as to how expensive/difficult the modification to any AU explorer manifold I might get is likely to be? thanks fellas |

I think the sensor is usually tapped in at runner #5 but you can easily insert it into the intake piping between the MAF and TB.

Just remember that this IAT sensor relocation will move the inlet air temperature reading below the adaptive learning window on all but the hotest of days (38°C and above), unless a chip is fitted with a reduced "minimum Intake Air Temp for adaptive learning". The stock setting for the adaptive learning window on all E-series V8's is 100 - 200°F = 38 - 93°C, which is set at this level due to the intake air heating as it passes through the manifold on the way to the temperature sensing point at the end of #5 intake runner. The best solution is to use the cobra (or EL2, GT40, early explorer) lower intake which already has the IAT boss in #5, next best is the chip, and finally weld a boss onto the original location. Running without adaptive learning takes away a lot of the benefit of electronic fuel injection, best to keep it in my opinion.

Wow, that's a brilliant write up, the sort of tech info that this site needs more of! Nice work dude. Just needs to be made into a full tech doc now.
Cheers ToranaGuy

thanks heaps for this, i've been trying to explain this to a few people.
the tubular manifold, does that run the same lower as the other explorer manifolds?

Yes, as mentioned in the first post, the lower intakes are the same except for the HO intake.
