Efficient fuel utilisation: With precise information about the air mass, the engine control unit (ECU) can accurately calculate the fuel quantity and supply it to the engine for the combustion process. Best quality: NTK mass air flow sensors are equivalent in quality and performance to the original equipment. Contribution to environmental protection: NTK mass air flow sensors contribute to an environmentally friendly combustion process by optimally controlling fuel quantity. Note: Please observe the general fitting instructions before installation! Scope of delivery: 1x NTK mass air flow sensor EPBMFN5-D003H
