Hella Intake Air Temperature Sensor

The Hella Intake Air Temperature Sensor (also called an IAT sensor or air charge temperature sensor) measures the temperature of the air entering the engine. It sends this data to the engine control unit (ECU). The ECU uses it to calculate air density and adjust fuel delivery and ignition timing.

Key Features:

• Uses a temperature-sensitive (NTC thermistor) element. Its electrical resistance changes with intake air temperature.
• Supports accurate air-fuel mixture control for smooth running, efficient fuel use and low emissions.
• Built to OE-quality standards by Hella, a long-established supplier of automotive electronics and original equipment.
• Direct-replacement design for straightforward installation.

A failing intake air temperature sensor can cause rough idle, hard starting, poor fuel economy, reduced performance or a check engine light. Replacing it with a quality Hella sensor helps restore proper engine management. Each part number in this product line is engineered for its specific application.
