This aftermarket BDFHYK unit replaces part numbers 213-3428 and 19112543 and is engineered to match electrical and physical fitment for Lesabre, Impala, Bonneville, and Camaro applications listed. Installing a correct-functioning MAF helps the engine control unit get accurate air-mass data so fuel delivery and ignition timing can adjust appropriately under load or idle conditions.\u003c\/p\u003e\n\n\u003ch3\u003eHow will replacing the MAF sensor affect drivability?\u003c\/h3\u003e\n\u003cp\u003eSwapping a faulty MAF for this BDFHYK sensor usually stabilizes idle and responsiveness by restoring accurate air measurement to the engine computer.
