Wells Mass Air Flow Sensor MAF Sensor

The Wells Mass Air Flow Sensor (MAF sensor) measures the amount of air entering the engine so the engine control module can calculate fuel delivery. A working mass airflow sensor helps the engine run smoothly, respond well, and use fuel efficiently.

Key Features:

• Measures incoming air volume and sends a signal to the engine computer
• Helps the ECM maintain the correct air-fuel ratio for drivability and emissions control
• Built as a replacement for the original sensor
• Made by Wells, a long-time supplier of aftermarket engine management and electrical components

A failing MAF sensor can cause rough idle, hesitation, poor fuel economy, stalling, or a check engine light. Replacing it can help restore proper engine performance. Choose the variant that matches your application from the options on this page.
