Looking for a intake manifold air temp guage what do guys, use does someone make such a guage.

 

This is the one I use, senders are sold separately

I have mine rigged with a toggle switch so the same gauge measures auto tranny temp. Intake temp sender is tapped into the airhorn. You are stuck with a digital gauge because most analogs won't read down to zero. The same outfit sells an air temp gauge whose range is -25°-150°F. I use the tranny gauge which is 0-300°F works excellent. Even jives with the outside temp when the truck is cold. Ideal intake temps are 50°-90°F, I have more trouble with my intake temp being too low in the winter than I ever do with it being too high. It's a 'fun' gauge, it moves around quite a bit. You'll like it with your Espar.

If the link doesn't work try searching for ZX470266B at www.jcwhitney.com

Looks like this

 

Bill do you ever see temps over 150 f?

 

I hit 175° for a short period once. It was a 102° day, I was climbing over a Montana pass with a trailer, near the top was a construction stop. The temp was about 130° till I stopped then went up fast. EGT, tranny temp and engine coolant were a little high but nowhere near excessive. Idling with the A/C was what did it, as soon as I turned it off the temp went down fast. Almost always the intake temp is 30° above the outside temp. The intercooler on these trucks does an excellent job, before I connected my extra sensor to the tranny I had it on the turbo side of the cooler, at 30 psi continuous boost would see close to 300° but it still cooled to 30° above ambient. Air is very easy to cool compared to a liquid.

So if you're asking whether to get the 150° or 300° gauge my opinion would be the 300°, both are accurate to 1°. Only difference is the 300 has a picture of an oil can on it, the air gauge has a picture of a thermometer.

I've added several of these Cyberdyne gauges on my tractors to monitor hydraulic fluid temp. All are doing fine even after over eight years of cabless tractor type vibration and dust including being parked outside in the snow all winter. Good product and price.

 

Autometer makes some pricey ones with memory recall.
