I wouldn't bother. All you are really going to get from a sensor on the intake is the heat soak temperature of the metal intake. you would be better off adding an air temp sensor to the air stream to show the real air temp. better yet wire it to the ecu if yours has that function and it will data log it and adjust the tune based on the actual air temp.

I did. and the result was temps that caused more problems than it solved. I ended up going with a GM air temp sensor. The temp numbers were useless. That sensor & location is only to detect a hot engine for the fans to run after shut off.

What SG said. If you want to measure intake *air charge* temperature you need a fast-reacting sender in the *air* stream.

If you want to measure intake *metal* temperature then the current switch location is fine.

In general, for a NA motor charge temperature should be lower than “metal” temperature.

In a boosted application you’d like it to be...

I ran both sensors to the same ecu and the air temp sensor was more accurate.

There are a couple of older and very informative threads on Rennlist that yielded results different from yours.

Post the links; i’ll look at’em.

Better off using your resources to tap the water bridge and add an after market water temp sensor that will give you the exact coolant temp. ...much more critical info.
