I agree. I was even contemplating a PLX system which can tie in to the OBDII to show coolant from the ECU, and oil temp from the PLX on my phone (torque app). Their sender is pretty long, and unless it can be spaced out there is obvious worry of restriction.

Autometer has this:

Designed for cylinder heads but same range as the other sensors so it fits all short sweep temp gauges. Would work good in a standalone app where custom resistances can be calibrated in, or if using autometer gauges is acceptable. I didn't really want to add an actual gauge to the RX8 (down by shifter), especially since I use my phone to watch coolant temp already when at track days.
