Where is best place for iat sensor for kpro

2002 RSX type-s
JRSC 3.0 inch pulley, approx 10psi
aftercooler in JRSC manifold
gm iat sensor directly under cooler core in JRSC manifold

My question is this, where would be the better place to get the intake air temp for Kpro from? I can use either the stock iat in my Injen cai, or I can use the gm sensor in the manifold, both are two wire with quick connects.

Reason I ask is when racing, iat in the cai will go up to about 104 degrees Fahrenheit whle waiting to race and drop 5-10 degrees during the 1/4 mile, while the temps from iat sensor in the manifold will go up about 50 degrees during a race, over a period of approximately 14 seconds. The gm sensor is fast acting, I am using it now for iat for Kpro, but would like to know if one or the other location would be better to use, or if it doesn't matter as long as a/f is correct.

Thanks for your time and response.

You shouldn't use a GM sensor. You should use an Integra sensor that bolts into the manifold. There is a place specially machined for it.

Yes, however I wanted to measure the air temps coming out of the cooler. The spot for the integra sensor is not the ideal for my purpose. I am aware that the gm sensor reads a few degrees low compared to actual.

Is the Integra sensor the same as a Civic SI sensor? There is about a $40.00 difference in price, Integra higher.

Another location that I am considering is in either the runner to cylinder number one, or cylinder number four. Air temps there would be in the 200 degree range.

So back to my original question, even using the spot for the Integra sensor, or the other two I mentioned, the air temps there will change in the opposite direction of the cai, the cai getting cooler, the manifold sensors getting hotter. Is one more desirable than the other, or does it not matter as long as a/f stays correct?

It should see the temps that the engine is actually ingesting air at.

I know it is not your responsibility to know what parts work with other parts, but would you know what year and model sensor works in that port on the JRSC?

The IAT sensor from any Integra (86-01)
