General Parts Update The recommended air filter for 2019 Model Year (MY) and newer 6.7L Cummins equipped vehicles has been updated. New Part: 68645327AA (Non-Oiled Air Filter) Replaces: 53034051AA (Oiled Air Filter) - This part is superseded and should no longer be installed. The air filter for all other applications remains unchanged: Continue to use 68517554AA for: All 2018 MY and older 6.7L Cummins equipped vehicles. All 2019 MY and newer vehicles with non-6.7L engines. 2. Special Service Procedure for DTC P0299 Application: 2019-2024 MY HD Trucks with 6.7L Diesel (ETM/ETN) Condition: If DTC P0299 is active and the vehicle is equipped with the previous oiled air filter (PN# 53034051AA). Procedure: Replace the oiled air filter (53034051AA) with the new non-oiled filter (68645327AA).
