Description
Aeroflow GM LS1 & LS2 High-Flow Thermostat – 180°F (81°C)
Engineered to optimize thermal efficiency and prevent engine overheating in GM LS performance builds.
Overview & Performance Benefits
Thermostats play a critical role in cooling system performance and engine protection. The Aeroflow Performance AF49-1144 high-flow thermostat opens at 180°F (81°C), which is lower than factory OEM units. By opening sooner and providing increased coolant flow, it maintains lower overall engine operating temperatures, leading to enhanced thermal and volumetric efficiency for maximum power output.
Constructed from heavy-duty copper and steel, this unit is a direct drop-in replacement for GM LS1 and LS2 engines without requiring any custom modifications.
