These OEM Mopar Gen-3+ thermostats are the lowest that we recommend utilizing in the Street application. They are direct fit for 1992-2002 applications, are stock replacement for 2003+, and offer a perfect balance of running temperature when combined with a revised fan routine on earlier models. Below 180 degrees, the Adaptive Trimming in earlier models can lock, and Check Engine Lights as well as performance degradation can result.
Note: Yes, Mopar is out of their minds on the pricing of these... but they are by far the most reliable option.
