This sensor is a must have for any k-swap. It reads the coolant's temperature and sends a signal to the gauge cluster in the EF/EG/EK/DC chassis. It easily threads into the Hybrid Racing Temp Sensor Adapter or any Hybrid Racing K Swap Radiator and is a must have for anyone doing a K-Swap in an older Honda chassis.

• Sends coolant temp to gauge cluster
