This Mass Air Flow (MAF) sensor from PIERBURG is designed to accurately measure the volume and density of air entering the engine's intake system. This critical data is then sent to the engine control unit (ECU) to determine the precise amount of fuel needed for optimal combustion. By ensuring the correct air-fuel ratio, this sensor contributes to improved engine performance, better fuel economy, and reduced emissions. A malfunctioning MAF sensor can lead to various drivability issues, including rough idling, hesitation, stalling, and poor acceleration. PIERBURG is a trusted name in automotive components, known for producing high-quality parts that meet or exceed original equipment specifications. This MAF sensor is built to provide reliable and consistent readings, helping to maintain your vehicle's peak operating condition.
