The OEM filter falls short with only 259 square inches of 25-micron filtration capability. The OEM filter’s leaf spring loses tension and can lead to dirty oil blow-by. The OEM bypass valve does not have a seal and allows unfiltered dirty oil to slip through.

In stark contrast, the PPE filter has superior filtration with 5-micron nominal rating, and 330 square inches of specially engineered media. A perforated metal center tube provides rigid media support.

The filter also includes a heat-resistant neodymium magnet to capture ferrous particles. This added layer of protection helps prevent internal engine wear and extends filter life.

The PPE filter’s upgraded bypass valve features a durable rubber seal and a stiffer spring, designed to maintain consistent oil pressure and prevent starvation in extreme conditions. A silicone anti-drain-back valve prevents engine dry starts. A stiff coil spring ensures a tight seal between the media and the base plate, eliminating oil blow-by.

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.
