Is your check engine light on with a code pointing to a bad MAF sensor? This Pleoos Mass Air Flow Sensor is a direct replacement for a ton of popular GM trucks and SUVs. It's built to be a sturdy, reliable swap for OE part numbers 10393948, 23256991, AF10060, and others. Before you blame the sensor, make sure you've got a clean air filter and air box – a dirty intake can throw false codes!

Compatibility is key – it fits a long list of 2009-2015 vehicles including: Chevy Silverado 1500/2500/3500, Tahoe, Suburban, Avalanche; GMC Sierra 1500/2500/3500, Yukon; Cadillac CTS and Escalade (mostly with 5.3L or 6.0L engines). PLEASE double-check your exact year, make, model, and engine size before ordering! Comes as one sensor. A straightforward fix to get your truck running smoothly again.
