Throttle body iceing??? w/ photo

[arz]

I have witnessed water droplets on the outside of my IC plumbing right before the TB, on top of the aluminum plumbing. The hose cant be leaking and I cant say where it could be coming from. Heres a photo of my setup its a Toyota Supra turbo motor in a 1971 Datsun 240 Z 2500 lbs @21 psi. Wheres the WI?? you say! Its top secret. Sorry no photo of actual ice but anyone got a good explanation. BTW I live in Mesa AZ and relative humidity is usually 10%-35% any other ideas would be great.
