The XDP Mass Air Flow (MAF) Sensor XD1054 is a direct-fit replacement for the faulty MAF sensor in your GM 6.6L Duramax LMM. The MAF sensor plays an important role by measuring the amount of air through weight-based voltage changes.

This vital information is then transmitted to the PCM/ECM, enabling precise fuel calculations for optimal engine performance. If the original sensor begins to fail, it can result in hard starts, engine surging, stalling, as well as a check engine light.

The XD1054 is built to meet the specifications of the original sensor for a direct-fit installation in the stock location.

Features:

• Direct-Fit Replacement
• High-Quality Construction
• Mass Air Flow (MAF) Sensor
• Measures Incoming Air For Proper Fuel Control
