Perfect for a lightly modded daily driver or a heavily modded track car, a lower temperature thermostat will ensure that your motor runs cooler. A lower temperature thermostat will also help to eliminate knock caused by excessive combustion chamber temperatures.
Which temperature thermostat should I choose? - We recommend the 180 degree thermostat for lightly modified supercharged vehicles and all naturally aspirated 3800s. We recommend the 160 degree thermostat for heavier modified supercharged vehicles in hotter climates. Most vehicles are very well suited with the 180 degree thermostat.
