Our Mass Air Flow sensors are designed as a direct replacement for the original parts. Mass Air Flow failure causes poor performance, poor mileage, stuttering, poor acceleration and will clog intake systems if left unchecked. A fully functional MAF sensor is critical for optimal performance.  Reprogramming of the vehicle's computer is not required for the MAF sensor replacement. Easy do-it-yourself installation. Please review the details section to verify this mass air meter is the correct part for your vehicle. The most common symptoms of a defective MAF are slow acceleration, poor gas mileage, rough idle, stalling, and engine stuttering. Also known as an air flow sensor
