Product Details
The Honda OEM Intake Air Temperature Sensor is a genuine factory replacement designed for a variety of Honda and Acura applications, including the Acura RSX, Honda Civic Si, Accord, CR-V, and Element.
Also known as the IAT sensor or air charge temperature sensor, this component monitors the temperature of the air entering the engine. The sensor sends temperature information to the ECU, allowing the engine management system to make appropriate fuel delivery and ignition timing adjustments for efficient combustion and consistent performance.
Over time, intake air temperature sensors can fail due to heat, vibration, contamination, or electrical faults. A malfunctioning sensor may cause rough idling, hesitation, poor fuel economy, reduced engine performance, or a check engine light.
Manufactured to Honda's original equipment specifications, this sensor provides accurate temperature readings, dependable operation, and factory-quality fitment. It is an excellent replacement for routine maintenance, engine repairs, and compatible K-Series engine swaps.
