Explorer Intake Act Sensor

[skerrybronco]

Doing the explorer intake swap, whats the best place for the act sensor, lower or upper intake, I need to drill and tap mine. I've seen a thread on this before but can't find it, any body know the size off hand.
also I have two neatly bagged in baggies when my vendor took everything apart, one has a closed cone and one has a cage, they seem clean, should I use one of these or buy new
thanks in advance

1/2"NPT I think. As for the two sensors, the cone one is water temperature, ect, engine coolant temperature. The air charge can go anywhere in the air stream. Could just mount it in the intake hose after the MAF sensor. Factory was in a boss in the lower intake. If yore using exploder lower it should have a spot for it.

It's my understanding that the explorer ECM is based on act data coming from intake tube NOT lower intake. Mustang and others were written for lower intake. Installing in lower intake might mess it all up. I'm not an expert, did not stY in HIE last night, but this is what I was told by an expert when I asked exact same question. I am planning to plug the port in my lightning intake and install act out in intake tube somewhere.

stayed up late reading
I'm running all mustang computer and stuff, so I think I will go in the boss of the intake
thanks, what you have said clarifies why they put it elsewhere

If you do the intake, do the lower. Getting all the metal chips out of the upper is impossible until you run the engine and let that suck them through.

I have had good luck with Mustang EFI by running the ACT hung freely in the engine compartment hanging out near the air filter.

there is a boss on the lower between #5 and #6 for this.. just use that.

thats what I will do, on my way to get the drill and tap, pipe thread sealer, and try to find something to clean out and strip the paint off the upper

I used airplane stripper in an aerosol can. Worked great. Easy.
