Spoon Sports - Thermostat, K20A (DC5, EP3)The Spoon racing thermostats promote greater cooling efficiency by significantly decreasing high engine temperatures resulting from modified applications. Once the engine is fully warmed up, the Spoon low temperature racing thermostat will open at a lower temperature than standard thermostats. This allows the coolant to flow through the engine sooner, thus reducing and maintaining cooler engine temperatures. OEM Starts opening at 78 Fully open at 90
