i have the low temp thermostat. LN does sell just the insert; it's $100. the car runs a little cooler with it in place, but the main thing i notice is that the temp is stable. it used to fluctuate a lot over about a 20deg range while i drove. now, the thermostat is fully open at operating temp, so everything seems a bit more steady.

i know this does virtually nothing once we're into the higher temp range, but it DOES get the coolant fully circulating a lot sooner, which makes for a more even temp across the engine mass. apparently hot spots can be an issue with these motors.
