[Working principle]The outside air into the throttle will flow through the sensor, into the engine will take a part of the heat, the greater the flow of outside air, take more heat in order to maintain the necessary temperature of the air flow sensor, it needs additional current to heat the sensor, it will regulate the size of the air flow through the current.[Replace in Time]When your car shakily, acceleration is weak, fuel consumption increases, black smoke from the exhaust pipe, etc indicating that your air flow sensor needs to be replaced.Replacing the sensor will fuel efficiency, assist the catalytic converter in better eliminating harmful gases from the vehicle's exhaust system, reduce emissions, and prevent premature catalytic converter damage.[NOTE] clean out the air box and replace the air filter installating this Air Flow Sensor Meter, or the Code and Check Engine Light may keep showing even if you replace a new Air Flow Meter Sensor measures the volume and density of air entering the engine, providing highly accurate readings to the ECU over a wide range of temperatures.Condition: NewItem Type: Air Flow SensorManufacturer Part Number: 06F906461AOther Part Number: AFH60M-27Interchange Part Number: 06F 906 461A, AFH60M27Fitment Type: Direct ReplacementNumber of Pin: 5PinsFit for:For A3 (8PA or 8P1) 2.0 TFSi, S3A4 (8EC or D, B7) 2.0 TFSiA6 (4F2 or 4F5) 2.0 TFSiTT (8J3 or 8J9) 2.0 TFSiFor (5P1 or 5P5) 2.0 TFSiExeo (3R2 or 3R5) 2.0 TFSi (1P1) 2.0 TFSi, 2.0 RToledo III (5P2) 2.0 TFSiFor II (1Z3 or 1Z5) 2.0 For (1F7) 2.0 TFSiGolf V (1K1 or 1K5) 2.0, 2.0 Golf VI (5K1 or 517) 2.0 , 2.0 R III (1K2) 2.0 TFSi (3C2 or 3C5) 2.0 FSi (137,138) 2.0 Rcolor:BlackMaterial:plasticPackage Contents:1 x SensorOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
