Placement of Intake Air Temp Sensor

[Drifty Midship]

I want to add an intake Air temp sensor in preperation for an Adaptronic install on a 4agze.
Just would like opinions on my proposed location.
What I want to do is put the sensor in a 45 degree 304 mandrel which will sit between the facroty IC outlet pipe and the Intake mani.
My concerns are that the mandrel will be quite close to the intake and probably get transfer of some of the heat... how much would this affect the sensor...??? Bad???
The other concern is whether this will adversly affect flow, having a sensor jutting into the intake tract so close to the manifold...??? Bad???
Any advice appreciated...
Cheers

As long as the sensor is in the airflow path it will work fine. Factory sensors are typically mounted on an alloy plenum which conducts heat way better than stainless and they seem to work fine.

put in a place where its going to get good flow across it, easiest place is the cooler/intake pipe just infront of the TB,

My air temp sensor came from a Commodore where it was located in the intake manifold itself. As such, that's where it ended up when my Adaptronic went on.

post TB would be better as it's going to reflect air temps inside the plenum, but pre-TB is also useful.

Get an open cage sensor that has a bakelite covering (as found in V6 commodes and othr bosch installs) rather than a solid brass unit as it will react faster to changes in air temp and be less prone to heat soak.

mine is in the pipe after the TB.

Other considerations include if you have Nitrous jet, the sensor should be a fair distance away from the jet, otherwise the cold gas flow will chill the sensor and produce readings that are too cold.
