Why remove thermostat from Subaru Impreza?

Removing the thermostat from a Subaru Impreza can be done for a few reasons, such as troubleshooting overheating issues or improving engine cooling in specific racing applications. However, it is generally not recommended for everyday driving, as the thermostat regulates engine temperature for optimal performance and efficiency. Without it, the engine may run too cold, leading to increased wear and inefficiency. It's crucial to consider the potential impacts on engine longevity and fuel economy before making such a modification.
