AdvanEX Mass Air Flow Sensor (MAF) for GM V8s 1999–2007 — Direct-Fit OE-Equivalent, 100% New

The AdvanEX Mass Air Flow (MAF) Sensor is a direct-fit replacement that measures incoming air to restore accurate engine air metering for select Chevrolet, GMC, Cadillac and Pontiac V8 models from 1999–2007.

If your vehicle is showing rough idle, reduced fuel economy, or check-engine codes tied to air intake, a worn or faulty MAF sensor can be the cause. This AdvanEX unit is engineered as a 100% new replacement to match OE electrical and airflow characteristics, supporting proper engine management and drivability for a long list of GM vehicles including Silverado, Sierra, Yukon, Denali, Suburban, Tahoe, Escalade, Rainier, Deville and Eldorado models.

How does this MAF sensor get your engine back to smooth operation?

The sensor measures the volume and speed of air entering the intake and sends that data to the engine control module (ECM). When the ECM receives accurate airflow readings it can adjust fuel delivery and ignition timing, which improves idle quality and throttle response.

• Direct-fit replacement for specified GM VIN and engine options.
• Matches OE connector, mounting points and electrical behavior.
• Helps eliminate air-fuel imbalance symptoms like stalling and hesitation.

Will this AdvanEX MAF fit my specific truck or SUV?

Fitment covers many GM V8 models from model years 1999–2007; compatibility depends on engine size and VIN code. Check the vehicle-specific fit list or your old part number to confirm match before ordering.

• Compatibility examples include Silverado/Sierra 5.3L and 6.0L, Yukon/Tahoe/Suburban V8s, Denali and select Cadillac/Pontiac V8s.
• Replaces common OE numbers such as 28411M, 213-4160, 25318411 and others listed by the manufacturer.
• Verify VIN letter and engine displacement against the product fitment table.

What are the build quality and reliability features of this replacement MAF?

AdvanEX supplies a brand-new sensor built with quality materials and tested for consistent output to match OE performance. The assembly is designed to resist vibration and maintain stable readings over time for dependable operation.

• 100% new electronic and sensing elements — not rebuilt or refurbished.
• Durable housing and connector designed for engine-bay conditions.
• Factory-style calibration to help ensure accurate airflow data for the ECM.

How long is the warranty and what support is offered after purchase?

AdvanEX includes a one-year after-sale service policy to address manufacturing defects or premature failures. The company requests buyers confirm fitment prior to installation and to contact support promptly if issues arise.

• One-year repair or replacement coverage for qualifying defects.
• Customer support available to troubleshoot fitment or installation questions.
• Appearance cosmetic issues don’t affect performance and are supported accordingly.
