2005-2008 Hyundai Tucson 2.0L and 2.7L engines are equipped with different air filter housings. If the incorrect air filter housing is installed, DTC P0171/P0174 (system too lean) may result.

When using the electronic parts catalog, be sure to input the vehicle’s VIN to obtain the correct part number.
