Is your truck running rough, stalling, or getting poor gas mileage? A faulty MAF sensor might be to blame. This replacement mass air flow sensor is compatible with a ton of GM vehicles: Chevy Silverado (1999-2007), Tahoe, Suburban, Corvette; GMC Sierra (2000-2007), Yukon; Cadillac Escalade, DeVille; and more with 4.3L, 4.8L, 5.3L, 6.0L, 6.6L, or 8.1L engines. It’s a 5-prong design that directly replaces OEM numbers like 25318411, 25168491, AF10043, and others. Comes with a fine mesh filter for accurate airflow readings. Installation is simple: disconnect the battery, unplug the harness, loosen the clamps, swap the sensor, and reconnect everything. Helps restore proper air/fuel mixture, improve performance, and lower emissions. A must-have fix for common GM truck issues.
