FAERSI Mass Air Flow Sensor for Chevy/GMC V8 V6 5.3L 6.0L - Direct Fit, OE Replacement

The FAERSI Mass Air Flow (MAF) Sensor is a direct-fit replacement sensor designed to restore accurate air-flow readings on compatible GM V8 and V6 vehicles, helping resolve flow-related fault codes and return engine responsiveness.

This FAERSI MAF is built as an aftermarket replacement for a range of GM models including Chevrolet Silverado, Suburban, Tahoe, Avalanche, GMC Sierra, Yukon XL, Envoy and Cadillac Escalade with 4.8L, 5.3L and 6.0L engines. It is designed to meet OEM specifications, swap into the original electrical connector and mounting, and substitute common OE part numbers such as 25168491, 25318411 and AF10043. Before ordering, check the vehicle year, make and model or compare OE part numbers to ensure a correct match.

How will this MAF sensor affect drivability and check-engine lights?

Replacing a failing MAF sensor with a properly matched FAERSI unit can correct incorrect air-fuel calculations that trigger diagnostic trouble codes and degrade throttle response. After installation, clear stored codes so the vehicle can relearn sensor readings and resume normal fuel trim adjustments.

• Resolves flow-related trouble codes when matched to the correct OE number.
• Restores accurate air mass data for improved idle and throttle feel.
• Requires ECU code clearing after fitment for immediate results.

Which vehicles and OE numbers does this part replace?

This FAERSI MAF fits a broad list of GM trucks and SUVs from late 1990s through 2000s; compatibility depends on engine and year. It’s sold as an aftermarket replacement for several factory part numbers, so verify the OE reference before purchasing.

• Common replacements: 25168491, 25318411, AF10043 and 19330121.
• Compatible models include Chevy Silverado, Tahoe, Avalanche, Suburban, GMC Sierra, Yukon XL, Envoy and Cadillac Escalade.
• Check your vehicle’s year/make/model or the original MAF part number prior to installation.

What should I do before and after installing the new sensor?

Prepare the intake area to prevent contamination and ensure accurate operation. Clean the air box and replace the air filter if dirty; after installing the new sensor, have stored ECU codes cleared so the vehicle can recalibrate using fresh sensor data.

• Clean the air box and install a fresh air filter before fitting the new sensor.
• Turn the ignition off during the swap and follow torque recommendations for mounting.
• Use a scanner to clear any remaining fault codes after installation so the ECU can relearn.

How reliable is the FAERSI MAF and what warranty support exists?

The FAERSI sensor is manufactured under controlled quality checks and tested for durability to match OEM performance characteristics. The product includes customer support and a one-year warranty offering a replacement if the part fails within the warranty period.
