E46 M3 Intake Air Temperature Sensor Location

After many in the community challenged the move it was proven in the end to be a great idea.

E46 m3 intake air temperature sensor location.

It s typically located in the intake manifold but may be in the airbox assembly on some models. It s typically located in the intake manifold but may be in the airbox assembly on some models. Air temperature sensors engine air distribution parts. Replace the intake air temperature sensor on my bmw quick fast and in a hurry.

The bmw e46 m3 utilizes the stock maf to pull intake air temperature iat readings however the location is not optimized for real world environment thus leading to heat soak and decreased engine performance. Secure the iat sensor into place using the supplied lock washer and nut. This is the m50 s50 m60 and m70 intake air temp sensor iat sensor for e36 325i m3 e34 530i 540i that sends intake temperature data to the ecu so it can correct for abnormally high or low intake temps.

This sensor is critical for peak engine performance and fuel economy. Our intake air temperature iat sensor relocation kit allows you to connect an external sensor to an optimized location to send the correct information to the ecu. E46 m3 intake air temperature sensor relocate s54 m3support was the first to offer the iat relocate years ago. 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.
