Overview
The Spoon Sports Low Temperature Thermostat is a genuine performance replacement for Honda B-series cooling systems. It begins opening at roughly 68°C — well before the OEM 76-80°C — and reaches full flow by about 81°C, circulating coolant sooner to hold engine temperatures down during hard street and track use.
Ideal for modified, high-output or track-driven B16, B18 and B20 engines where controlling coolant temperature protects power and reliability. A flow-control-type valve resists temperature hunting for quicker, more stable warm-up and running temps.
