E46 M3 Intake Air Temperature Sensor Location

This sensor is critical for peak engine performance and fuel economy.

E46 m3 intake air temperature sensor location.

Secure the iat sensor into place using the supplied lock washer and nut. It s typically located in the intake manifold but may be in the airbox assembly on some models. Intake air temperature sensor e36 e46 e39 e38 x5 z3. The intake air temperature iat sensor is integrated into the e46 m3 stock maf location inside the intake tube and although the oem location works it is prone to heat soak which will allow the ecu to pull timing resulting in power loss.
