In this video I installed a 200°F (93°C) thermostat for my Mishimoto oil cooler. The oil cooler sandwich plate from Mishimoto originally came with a 185°F (85°C), but with cold ambient temps the oil never gets to operating temperature where it stays around 170°F. I wanted the oil to stay around 190°F+ so I went with the 200°F thermostat. Oil temps now stay at the optimal temperature range of 185°F - 210°F (depending on ambient temp). I highly recommend anyone with a Mishimoto oil cooler kit to upgrade to the 200°F (93°C) thermostat to maintain the optimal operating oil temp.
