Application in BMW N47 Engines

The hot air mass meter in this model works with the intake system of BMW N47 engines installed in the E81, E87 LCI, and E90 series. It is a component designed to operate in the demanding environment of diesel units, where the following are crucial:

• stable air mass measurement under varying engine load,
• cooperation with the diesel injection system's control electronics,
• resistance to intake air temperature fluctuations.

Thanks to proper adaptation to the specific generation of N47 engines, the mass meter supports the correct operation of the intake system and reduces the risk of errors related to the fuel-air mixture.

Technical Characteristics and Compatibility

The offered component belongs to the group of accessories related to the intake manifold, responsible for controlling the amount of air supplied to the cylinders. The design of the mass meter is adapted to the specifics of a Diesel engine, where the following are important:

• accurate flow reading at low and high RPMs,
• proper cooperation with the turbocharger and exhaust gas recirculation system,
• stable operating parameters during extended use.

The product has assigned part numbers and interchangeable numbers, which facilitates verification of compliance with a specific vehicle configuration. Before purchasing, it is advisable to compare the designations with the vehicle's factory data to ensure full installation compatibility.

Condition of the Component and Benefits of Choosing a Used Mass Meter

The hot air mass meter is offered as a used part, which allows for significant cost reduction compared to new OEM components. For BMW users, this means the possibility of restoring proper intake system operation while maintaining a favorable price-to-quality ratio.

Choosing a used mass meter for a diesel engine is particularly attractive in situations where:

• ECU errors related to air mass measurement occur,
• the engine loses dynamics or runs unevenly at low and medium RPMs,
• a quick and economical replacement of the component in the intake manifold system is necessary.

Why Choose This Hot Air Mass Meter

The model dedicated to BMW E81, E87 LCI, and E90 with N47 engines ensures adaptation to the factory intake system architecture. This allows for smooth installation, and the engine control unit receives reliable data on the amount of intake air. This translates to:

• more predictable throttle response,
• more efficient operation of the diesel injection system,
• reduced risk of the unit entering limp mode due to incorrect flow readings.

For owners of BMW cars with N47 engines, this is a practical solution that allows maintaining the efficiency of the intake system without the need to invest in a new component.
