Ait Temp Sensor placement in lower intake?

[BIGONTS]

Thinking about relocating my IAT sensor while I have the motor out and intake coated. Did some research and both Cal and Julio don't see a problem with the sensor in the lower intake as far as overheating, accuracy, etc.. I don't care for it in the upper intake either on the rear or side of the doghouse.

Let me know if this is a good spot, just left of the rear center upper intake bolt? Seems likeit would not interfere with the coil pack bracket or anything else. I run a dual alky kit and a classic FAST along with the mods in my sig.

Any input is greatly appreciated. Thanks

Also, does anyone got a part number for a new IAT sensor? I need one and don't know if I should just go to NAPA or dealership??

thats about where i have mine

Looks good. I was thinking more towards the driver's side and closer to the plug on the wire harness. Does the plug have to be extended or will it reach the back of the intake? I see Caspers sells 12" extensions and I wonder if that will be enough, or necessary??

i just pulled mine out of the wire loom, if you want to go through all of that.

Same here. Also, does it make a huge difference one way or the other if the sensor is placed before or after the MAF, intercooler, etc?

By my thinking, it seems like it would make a difference, since the air going into the engine is going to be a bit hotter than the air outside, and the ECU would change calculations based on that, right?

Subscribed. I'd like to know the answer to that too. Seems to me that even after being cooled the air temp in the manifold has got to be much warmer than ambient air. Surely the sensor sees that temp, and if it doesn't adjust accordingly then why even have one?

i think it will just add some fuel to compensate for the higher temerature reading

it will take away fuel for a higher temp reading. that's why it's always been sort of a "speed" trick to move the temp sensor farther away from the engine on some cars. it thinks the incoming air is cooler, so it adds fuel.

I think it all depends on what computer you use and how the IAT sensor is being utilized. I have a classic FAST and I'm going to use the IAT more for monitoring temps as they relate to the alky and make some adjustments. The tuning is done mostly by reading and adjusting to the wideband o2 readings, etc.. .

This is my understanding of it and maybe someone who has more knowledge how the IAT sensor is utilized can chime in.

I put mine dead center it sticks out a good way in to the intake then I drilled an extra hole high and to the right for a vacuum block and I did a way with the TB vacuum block. here are some pics
