Thermostat 160 Degrees GM LS1

The MR. GASKET Thermostat 160 Degrees for GM LS1 engines is a precision cooling component designed for high-performance LS-platform builds and street-to-strip applications. Effective engine temperature management is crucial for reliability and performance in LS1-powered vehicles. This thermostat is engineered to open at a lower threshold than standard OEM thermostats, allowing for improved coolant circulation.

By opening at 160°F, this thermostat helps to reduce thermal stress and optimize combustion efficiency, making it suitable for both forced-induction and naturally aspirated setups. Its compact design integrates seamlessly into the stock LS1 thermostat housing, and its lightweight construction ensures no significant impact on underhood weight distribution.

This thermostat is particularly beneficial for LS1 owners running turbo or supercharger kits, as well as those with aggressive tuning setups, where maintaining optimal engine temperatures is essential for performance. It is also a great choice for naturally aspirated track cars and street machines, ensuring stable coolant flow for reliable operation.
