IAG 156 DEGREE LOW TEMPERATURE "EJ" THERMOSTAT FOR 2002-2014 WRX, 2004-2021 STI




IAG 156 Degree Low Temperature Subaru EJ Thermostat for WRX STI

THE IAG 156 DEGREE LOW TEMPERATURE EJ THERMOSTAT

For Subaru owners pushing their 2002-2014 WRX or 2004-2021 STI EJ series engine to the limit, the IAG 156 Degree Low Temperature EJ Thermostat is a smart upgrade. Unlike the factory thermostat, which doesn’t open until 172.4°F (78°C), this unit starts opening at 156°F (69°C), improving cooling efficiency by allowing coolant to circulate sooner.

ENGINEERED FOR PERFORMANCE

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.

The IAG 156 Degree Low Temperature EJ Thermostat is engineered for durability, featuring a 304 stainless steel body to resist corrosion. This direct-fit replacement stands up to demanding conditions and includes the necessary gasket for a secure, leak-free seal to the thermostat housing. Every detail, from the laser-etched finish to the IAG corporate logo is a reflection of the high quality engineering and construction behind this component.
