Default BEGI-S IAT question

The elbow right before the throttle body has a 1/8 NPT bung. I assume it's for an IAT sensor. I was planning to use a 3/8 NPT GM sensor. Does anyone know of a 1/8 NPT IAT sensor that similar to the GM open element?

It's not. It's for the IAC (idle control valve) hose isn't it?

I have a 99 which doesn't have an idle control valve hose so I have no reference but that hose looks a lot bigger in pics.

I like the WI idea.

ZX-Tex just drilled and tapped the wall of the inlet tube. I may do that. I need to switch to an IC before next summer so it would be temporary anyway.

Yup- the NA idle air bypass hose is appx. 1/2" ID or so (just eyeballing) and it's a slip-fit. Like Brainey said, a water-injection nozzle is about the only thing I can think of with a 1/8" NPT thread that you'd want to put in that location.

It should be a 3/8NPT. Shoot me an e-mail or PM, and we will get you the correct tube.

Looks like the Saturn Ion coolant sensor is 1/8" NPT but uses the same connector as the standard one. Useless for me but it might be useful info for someone doing a coolant reroute or some other cramped install.
