• MicroPure XR® filtration with a 5-micron nominal rating
• 330 Square inches of ultra-fine synthetic microfiber media, a 70% increase over the stock filter
• Integrated high-temperature rated neodymium magnet captures ferrous particles, providing extra engine protection
• Built-in bypass valve with precision coil spring and steel-NBR poppet
• High-strength steel base plate with increased thread engagement and large oil passages
• Durable metal center tube provides excellent media support and pressure resistance
• TorqSTOP™ Technology prevents over-tightening and reinforces the gasket against high oil pressures
• Silicone anti-drainback valve delivers superior protection during engine start-ups
• Heavy-duty coil spring ensures a secure seal and prevents oil blow-by, maximizing filtration performance.

The oil filter is your engine’s first line of defense against contaminants that degrade oil performance and reduce oil lifespan. Poor filter performance and the presence of oil contaminants can lead to premature wear and potential failure of engine internals. The OEM filter falls short, only offering 259 square inches of 25-micron filtration capability and using a weak leaf spring, reducing seal quality and allowing dirty oil to blow past the filter media.

PPE’s upgraded filter provides 330 square inches of filtration area, a 27% increase over the OEM filter. The specially engineered ultra-fine synthetic microfiber MicroPure XR® media achieves a 5-micron nominal rating. An integrated high-temperature rated neodymium magnet also allows the PPE filter to capture ferrous particles, preventing them from clogging the media, extending filter and oil life. The use of a heavy-duty coil spring ensures a secure seal between the media end cap and the base plate, eliminating dirty oil blow-by and maximizing filtration performance.

In contrast to competitors’ unsealed bypass valve, the PPE filter incorporates a steel-NBR poppet and a precision coil spring to ensure a proper seal and consistent performance. The PPE filter also features a heat-resistant silicone anti-drainback valve, retaining oil in the filter after the engine is turned off for superior protection against dry starts.

The PPE filter’s heavy-duty construction, consisting of a high-strength steel base plate with increased thread engagement and large oil passages as well as a durable metal center tube for rigid media support and pressure resistance, allow for maximum confidence in all conditions. Additionally, PPE’s TorqSTOP™ Technology prevents over-tightening and reinforces the rubber gasket, enabling a burst pressure rating of 450PSI.

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.
