No one thinks about the thermostat until they're on the side of the highway with the hood up.
The 3.6L Pentastar is a solid engine, but the factory thermostat keeps coolant locked out longer than it should, and if you've added a tune, a supercharger, or are towing anything with some real weight, that heat has nowhere to go.
The RIPP 180° thermostat housing is what you put on before that becomes your problem. Gets coolant moving sooner, keeps temps where they actually belong, and it bolts right in.
Fits 2016–2026 Grand Cherokee and Durango.
