- [11025040](https://open.wenmarpro.com/bulletins/11025040), 2025-11-05: 1. 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 New Part: 68645327AA \(Non\-Oiled Air Filter\) Replaces: 53034051AA \(Oiled Air Filter\) \- This part is superseded and should no longer be installed.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 \(68645327AA\). Service Catalog reflects these updated usages.
