I'm about to install a Snow Performance Stage 2 water methanol kit on my supercharged AUXR8 Windsor and have a dilemma about where to install the nozzle. After reading numerous posts on other forums and writeups on websites, I'm still unsure. Snow Performance says to put it next to the throttle body, but this is after the IAT (or AIT) sensor that measures the hot air coming out of the SC.

If the IAT doesn't know the air is cooler going into the engine, how does the ECU know to adjust the advance? Some comments, that I read, said not to install the WM nozzle before the IAT as it will end up recording the WM rather than the air temp and become 'wet'.

Is it necessary for the IAT sensor to be installed in the EGR spacer, or in the upper Explorer manifold somewhere?

Can anyone advise on this please?
