Can i see someones set up and how you did it? Thinking about it.
Would you just block off the stock location and make your own new one? The intake isn't going to be stock much longer either.

I drilled a hole, installed a grommet, installed the sensor in the plastic CAI tube down closer to the filter. I then extended the wire harness so it would reach. I then put a second IAT sensor in the original location obviously unplugged.

ill ask the stupid question, why would you want too? I thought the IAT had to be post MAF?

Thanks, are you just running a CAI or a lid or...

I'm still researching it but it supposedly gives a more accurate reading if you do this. Being closer to the filter, not getting heat soaked from the engine bay.

makes sense to me. use datamaster and try both locations and see if you get much differant of a reading or not and then you will know if its worth anything

I have a K&N FIPK CAI. The datamaster absolutely confirms that the IAT temps are much more accurate when relocated to to the CAI as opposed to the stock location.

How would the sensor get heat soaked? Even under part throttle it has more than 1 cubic foot/sec of air moving past the sensor, which has a plastic body. Being that the PCM uses the IAT input to control fueling and spark, I'd like it as close to what the engine is actually seeing vs what we would want it to be. Relocating the sensor to see IAT at the filter will produce more consistent but not necessarily accurate readings.

Cant speak to the physics of air, its above my pay grade.

But I can say this. With a motor at full operating temps last week when the outdoor temps were in the mid 90's, with the IAT sensor in the CAI near the filter, the scanmaster said 102 degrees while the motor was at idle. Turned the motor off, switched the harness to the sensor in the elbow and it said 118 degrees.

If I turn the motor off and restart it in 5 minutes, the reading with the sensor in the elbow is consistently much higher at restart as opposed to the sensor in the CAI.

What does all this really mean? Hell if I know!

That tells me your engine isn't seeing ambient air temperature, and your sensor reflects that.

If the PCM sees air that is cooler than what it actually is at the intake, won't it fatten the mixture a tad and give you an artificially rich condition (slightly)?

something like that yes

thats what i was thinking, i just figured the air directly outside of the throttle body is what gets sucked in, so wouldnt you want the computer to give you the correct fuel mixture and spark timing to burn THAT air, rather then the air thats 3 feet outside of the engine that will be getting warmed up anyways?
