Product Description
MOPAR 68430063AA INTAKE AIR TEMPERATURE (IAT) SENSOR FOR 03-07 DODGE WITH 5.9L CUMMINS ENGINE
Maintain optimal fuel delivery, turbocharger efficiency, and overall engine performance with the genuine Mopar 68430063AA Intake Air Temperature (IAT) Sensor for 2003-2007 Dodge Ram trucks equipped with the legendary 5.9L Cummins turbo diesel engine. This OEM intake air temperature sensor is engineered to accurately monitor incoming air temperatures within the intake system, allowing the engine control module (ECM) to precisely adjust fuel mapping, timing, and air-fuel ratios for maximum diesel performance and efficiency.
The Mopar 68430063AA IAT sensor is a direct-fit OEM replacement designed specifically for Dodge Ram 2500 and 3500 Cummins applications. Mounted in the air cleaner housing, this sensor plays a critical role in calculating air density and combustion efficiency under varying operating temperatures and load conditions. A failing intake air temperature sensor can contribute to poor fuel economy, hard starting, excessive smoke, reduced throttle response, and diagnostic trouble codes.
Manufactured to strict Mopar OEM standards, this sensor provides dependable readings, factory connector compatibility, and long-lasting durability under demanding diesel operating conditions. Unlike low-cost aftermarket alternatives, genuine Mopar sensors deliver accurate calibration and seamless integration with the factory ECM system.
This OEM sensor replaces multiple previous Mopar and Cummins part numbers while maintaining factory-level reliability and performance.
