I've gone through about 15 threads in the search archives looking for info on this and what I've gathered is that speed density setups rely more heavily on correct IAT sensor readings because they contribute to the PCM's fuel table adjustments.

Here's where I'm at:

I've done a custom air intake setup that has completely deleted the intake elbow and armature. I have a custom aftermarket water neck that allows clearance and I've installed a K&N cone shaped air filter directly onto the throttle body. I'm running a ramair hood that's been made functional and the opening is directly above the air filter. Because I won't have an elbow or intake tube to mount an IAT sensor in, I'm looking for suggestions on where would be the most ideal location to put this. Most of the people who have contributed info on this topic had MAF cars and it appeared that all they needed to do was get the sensor away from the engine to prevent it from being heat soaked but I'm not sure whether that will be satisfactory for a speed density setup. I'm 100% sure that the resistor mod is out of the question.

I've relocated my battery to the trunk and removed the stock coolant overflow tank and have an aftermarket stainless one. There is plenty of clearance around the new overflow tank down in that cutout where the stock piece used to reside. Would that be a good place?

The IAT data is used to calculate the air density in speed-"density". The more accurately the IAT measures the air that's actually entering the engine, the more accurate the PCM calculates the mass air flow into the engine.

I put the IAT sensor in the metal cap on my K&N filter. Drill a hole just slightly larger than the sensor, put a rubber grommet in it, and push the sensor into it.

Thanks Fred.
