Review on 🚀 Jet Performance 10183 High-Performance Thermostat by George Jacobson

Fantastic product. Perfect fit for my 2017 Jeep SRT 6.4 (392). Installation took about 10 minutes with a 13mm head and ratchet. The stock thermostat ran at about 215/220 in 82 degree weather. After installation without tuner for fan setting (standard fan setting still works), the temperature remains stable at 185/190 when driving in the city/highway. If you get stuck in traffic, maybe 200/210, but as soon as you start driving again, go back to 185/190. Very good mod for what it costs.
