The AdvanEX MAF is 100% new and built to match OE electrical and airflow characteristics for many GMC, Chevrolet, Cadillac and Pontiac V8 models. It restores accurate air measurement to the engine control module (ECM), helping maintain correct fuel metering and engine response.\u003c\/p\u003e\n\n\u003ch3\u003eWhich vehicles and engines does this AdvanEX MAF support?\u003c\/h3\u003e\n\u003cp\u003eThis sensor fits a wide range of GM full-size trucks and SUVs from the late 1990s through the 2000s.
