Yezoauto MAF Sensor for GM V8 Engines — Direct-Fit for 5.3L/4.6L Models, OE 25318411

Yezoauto Mass Air Flow (MAF) Sensor — a direct-fit replacement engineered to restore accurate air measurement and return smooth, predictable engine performance for compatible GM V8 models.

If your Buick, Cadillac, Chevrolet or GMC with a compatible V8 is showing rough idle, poor throttle response, or reduced fuel economy, a failing MAF sensor is a common cause. This Yezoauto unit is built to match OE specifications and communicates airflow data to the powertrain control module so fuel delivery stays balanced with incoming air. It’s precision-made, bench-tested, and supplied with reference OE numbers for easy cross-checking before purchase.

How will this MAF sensor affect drivability?

Replacing a worn or faulty MAF sensor helps the engine computer calculate proper fuel injection, which typically cures hesitation, erratic idle, and stalling. A correct airflow reading also helps the vehicle maintain intended torque and acceleration behavior under load.

• Restores accurate air-to-fuel estimation for smoother idling and acceleration
• Reduces misfires and hesitation during throttle changes
• Improves consistency in engine response under varying driving conditions
