Genuine 13345245 Mass Air Flow Sensor with Housing

The Genuine 13345245 Mass Air Flow Sensor is a GM original equipment component designed to measure the amount of air entering your engine for optimal performance and fuel efficiency. This sensor measures the volume and mass of incoming air and signals this information to the engine control module (ECM), which uses the data to calculate the precise amount of fuel to inject for the ideal air-fuel mixture.

Key Features:

• GM Genuine Parts original equipment quality and fit
• Includes complete sensor assembly with housing and mounting hardware
• Hot wire sensor technology for direct air mass measurement
• Factory calibrated for accurate readings across all operating conditions
• Ensures efficient air/fuel mixture for best fuel economy, power, and reduced emissions
• Direct replacement for worn or failed original sensor

A faulty MAF sensor may cause hesitation under acceleration, stalling, and incorrect air/fuel mixture, often triggering a check engine light. The sensor is located between the air filter and throttle body along the air intake stream, making replacement straightforward with basic hand tools. This genuine GM component ensures your vehicle maintains the performance, durability, and emissions compliance it was designed to deliver.
