For Subaru owners pushing their 2015+ WRX and 2013+ BRZ FA series engine to the limit, the IAG 76 Degree Low Temperature FA Thermostat is a smart upgrade. Unlike the factory thermostat, which doesn’t open until 190.4°F (90°C), this unit starts opening at 167°F (75°C), improving cooling efficiency by allowing coolant to flow earlier. By lowering operating temperatures, it helps prevent heat soak and improves thermal management—ideal for high-performance driving where maintaining optimal engine temps is crucial. By allowing coolant to circulate earlier, a low-temperature thermostat helps to keep the engine from heating up too quickly. This is a big advantage for engines that see heavy loads, preventing sudden spikes in heat. A cooler engine can also mean better efficiency and less risk of detonation, allowing for stronger, more reliable performance.
