I'm using the Mishimoto sandwich plate with the 200 degree thermostat. My oil pressure gauge connects to a T that goes into the existing low oil pressure sensor. My oil temperature gauge is remotely connected to the sandwich plate. Both gauges work great.Thanks for the datapoint. Are you using the stock sandwich plate with 200F thermostat or an aftermarket sandwich plate? Also, where are you tapping the oil temperature from (pan or plate)? Thanks!
