RLP Mass Air Flow (MAF) Sensor accurately measures incoming air for compatible Cadillac, Chevy and GMC engines, restoring proper air-fuel balance and engine response.

This direct-fit replacement MAF sensor is manufactured to match OE airflow characteristics and electrical outputs for a long list of late‑2000s and early‑2010s GM trucks and SUVs. Built with precision sensing elements and quality components, the unit is designed to give consistent readings across a range of ambient temperatures and driving conditions. It replaces part numbers 10393948 and 23256991 (also listed as AF10060, MAF300, 917-1067, 5S13836) and fits in the air intake path near the factory airbox for straightforward access.

How will this MAF sensor affect drivability and engine performance?

Replacing a worn or failing MAF restores the engine control unit’s ability to calculate correct fuel delivery and ignition timing. Expect smoother idle, quicker throttle response and more consistent acceleration when the air intake is being measured accurately.

• Improves air-fuel ratio accuracy for better combustion
• Reduces rough idle and hesitation
• Stabilizes performance under load and varying temperatures

Which vehicles and part numbers does this unit fit?

This RLP MAF is designed as a direct replacement for many GM models from approximately 2009–2015. Verify exact fit using vehicle details before purchase to ensure compatibility with your make, model and trim.
