Due to changes in the thread of the temperature sensor on the cylinder head of the Euro4 version of Derbi Senda, Aprilia RX / SX and Gilera RCR / SMT, the sensor cannot be mounted on tuning cylinders. Therefore, this adapter must be used for the temperature sensor to be mounted.
Mounting the temperature sensor is a prerequisite for a successful mounting of the tuning cylinder, as the sensor is connected to the ECU / CDI.
The adapter goes from M12x1.5 (internal) -> M14x1.5 (external) thread.
