2020-2025 GM 6.6L Duramax Premium High-Efficiency Engine Oil Filter

Premium High-Efficiency Engine Oil Filter

The 2020-2023 L5P PF26 falls short in protecting the L5P engine with only 259 square inches of 25-micron filtration capability, and the 2024-2025 L5P is equipped with an even smaller PF63 filter. That's why your L5P deserves the PPE filter.

The PPE filter has 522 sq. inches of specially engineered 5-micron filtration media, doubling the size of the stock PF26 filter. The perforated metal center tube provides sufficient media support while the bypass valve is guarded by a rubber seal to prevent unwanted blowby.

This filter also includes a heat-resistant neodymium magnet that traps ferrous particles, preventing them from clogging the filter or damaging engine components. A silicone anti-drain-back valve prevents engine dry starts. The oil passages are enlarged for unrestricted oil flow, and the threaded plate is made thicker and stronger to accommodate this change.

Note: 114002700 Fuel Coolant Pump Relocation Bracket Kit is required for the install of this deep filter.

From 2020 to 2023, the GM 6.6L Duramax utilized the PF26 oil filter. In 2024, the Duramax transitioned to the PF63 oil filter, which features larger passage holes for improved flow but is the same filter used for the 5.3L Small Block, possessing smaller filtration media and getting clogged easier.

The PPE Premium High-Efficiency Filters 114000740/114000750 are compatible with the 2020-2024 Duramax, offering superior flow, increased capacity, and enhanced protection over both the PF26 and PF63 filters.
