Just finished riding through some serious rain. Dew point 76, humidity 96%, air temp 75-78. Went through some accumulated water puddles that caused big splashes under the driver side wheel well. Parked my truck, popped the hood and air filter was not damp, no water residue in the bottom of the air box, no sign of moisture in intake tubes. Unless it all dried up in 10 minutes. Although i don't think I ever experienced the effects of the condinsation issue, I just wanted to see and report in the real world. After seeing the test from germaneb, unexpected atleast a damp filter

I too have driven thru some heavy rain and checked my filter immediately--no water. The only time mine has even had any kind of stumble at all was on a trip through Amarillo when I drove for 2.5 hours at steady speed when the humidity was 95% and temp was around 80. It just hesitated with hardly any power for just a few seconds and then took off. Has never done it again.

it is humidity causing condensation build up in the intercooler.

^ This. There's only about 200 threads on this problem. It's well documented.

MadocHandyman

He's reporting on GermanEB's theory that it's coming in from the intake. Not sure which thread it was discussed in.

Oh it's coming in from the intake all right.......it's just not liquid when it does.

And GermanEB is not the only one who posted something like that as I recall FR Geoff posted that theory as well from on of his ford engineer buddies.

All 4 engines use the same airbox. And only one has the condensation problem......Hmmm I wonder...

mr_diggs

Does your EB intake box have a short plastic tube that leads directly to the throttle body? Or is it one of those intakes that has 12ft of plastic tubing leading from the airbox>tube(s)>turbo inlet(s)>tube(s)>intercooler>tube>throttle body? See what I'm saying?

All the EB have about 15 ft of plumbing before it goes to the TB. The intake boxes themselves are all the same.
