This Mass Air Flow (MAF) sensor is designed to precisely measure the amount of air entering your engine. This critical data allows the engine control unit (ECU) to calculate the correct amount of fuel to inject, ensuring optimal combustion, performance, and fuel economy. As a direct replacement for the original VAG part 03H906461A, this sensor guarantees compatibility and ease of installation. Maintaining the integrity of your air intake system is crucial for engine health, and a functioning MAF sensor is at the heart of this system. Symptoms of a failing MAF sensor can include rough idling, poor acceleration, decreased fuel efficiency, and illuminated check engine lights. Replacing a faulty sensor with this high-quality part can restore your vehicle's performance and prevent further engine issues.
