Nissan SR/KA Silvia Nismo Low Temp Thermostat

Keep your engine cool under pressure with the Genuine NISMO Low-Temperature Thermostat. Engineered specifically for high-performance driving, track days, and hot climates, this thermostat is an essential cooling upgrade for your Nissan S-chassis. ​By dropping the coolant activation threshold, NISMO allows your radiator to start working before heat soak robs your engine of power and responsiveness. ​Why Upgrade to NISMO? ​Earlier Coolant Circulation: While a standard factory Nissan thermostat waits until 76.5°C (169.7°F) to open, the NISMO unit opens early at 62°C (143.6°F). This gives your cooling system a vital head start. ​Prevents Power Loss: High-speed driving and track conditions quickly drive up engine temperatures, triggering the ECU to pull timing and reduce power. This thermostat helps maintain optimal operating ranges to ensure peak performance. ​Ideal for Modified Cars: Highly recommended for turbo-converted or high-boost applications where thermal management is critical to protecting internal components and extending engine life.
