I prefer to leave it in for any car driven on the street - it does a good job of bringing the oil up to temp more quickly, and with the cooler in place, the oil rarely runs more than 20*F higher than the coolant temp, so it's not putting much heat back into the cooling system at operating temp.
For track cars, you can delete with the B6 filter stud.

I'd like to put out a call for data. Ideally, someone will be able to measure oil temps pre and post cooler. But, this requires two gauges. Failing that, any data on post-cooler oil temps (before re-entering the engine) would be good. The goal here is to get a feel for exactly what kind of delta-t we are seeing through an oil cooler in our cars.
Please include
a) usage conditions (track, autocross, texas mile, etc)
b) ambient temps
c) oil temp(s). If only post-cooler oil is being measured, please include an estimate of oil temps pre-cooler for that car under similar conditions, if known.
d) oil cooler in question, and how it is ducted (or plumbed, if oil<->water)

Very true, I'll try and figure out how to get a post cooler temp. I bet if I teed off the pressure sensor I could do it.
Would this work:
Pre cooler temp in sandwich plate underneath mocal plate.
Post cooler temp in pressure sender port?

By pressure sender port you are referring to the stock one? I don't have the miata oil flow path memorized, let me look around.
Edit:
Hmm, I don't know. According to this diagram, it looks to me like by the time the oil gets from the filter to the oil pressure port, it may have equalized to whatever the block temperature is at that point. Iron transfers heat good.
