Detailed Product Description

The AX68 sensor from Standard Ignition is engineered to provide accurate intake manifold temperature data to the engine control unit (ECU) in Dodge Ram 2500 and Ram 3500 trucks. Featuring a plug-in attachment method and a single female oval connector, this sensor simplifies installation and ensures a secure electrical connection.
