The Hyundai part number 28164-27800 corresponds to a Mass Air Flow (MAF) sensor primarily designed for Hyundai and Kia 2.0L, 2.2L, and 2.5L CRDi diesel engines, rather than the 6-cylinder (V6) petrol engines.
If your Santa Fe features a 6-cylinder petrol engine (such as the 2.7L, 3.3L, or 3.5L V6 common between 2000 and 2012), this specific part number will likely cause a mismatch. 6-cylinder petrol versions generally utilize different part numbers, such as 28164-37200 or 28164-3C100
