Description
xUpgrade your GM V8 with the Yezoauto Mass Air Flow Sensor
The Yezoauto MAF sensor is designed as a precise, direct replacement for a broad range of GM V8 engines. By detecting the volume of air entering the intake, it helps the engine control module determine the ideal air–fuel mix. This balance supports smooth acceleration, steadier idle, and a responsive feel when you press the accelerator.
Built to perform under real driving conditions, this sensor uses precision sensing elements and state-of-the-art testing to restore the original drivability you expect from your vehicle. Its fast response time helps the PCM react quickly to changes in air flow, while its lightweight, easy-to-install design makes it a convenient maintenance upgrade.
- Compatibility across a wide range of GM V8 models, including Buick Rainier, Cadillac Eldorado and Escalade, Yukon and Envoy families, Chevrolet Avalanche and Silverado line, Hummer H2, Pontiac GTO, Saab 9-7X, Isuzu Ascender, and more.
- Reference OE numbers such as AF10043, 213-4160, 213-364, 15904068, 25168491, 25318411, 8253184110, MF8411, 28411M, and others ensure accurate fitment.
- High-quality sensing elements and rigorous 100% quality inspection support dependable performance.
- Fast response, durability, and a lightweight design make installation straightforward and long-lasting.
