High-Efficiency Engine Oil Filter for 2020+ GM 6.6L Duramax (replaces AC Delco PF26).
This oversized PPE Engine Oil Filter features 2 times the specially engineered filter media, equaling 522 square inches, which is over 100% larger media than OEM.
A spiral-wrapped adhesive and perforated metal center core provide media support, preventing collapse.
A high-power magnet is included to catch ferrous metal debris, preventing it from circulating or clogging the filter paper.
The silicone anti-drain-back valve prevents engine dry starts.
The bypass valve has a stiffer spring and a rubber seal.
The base plate is thicker to accommodate increased oil pressures in high-performance applications.
The OEM PF26 filter has only 259 square inches of 30-micron filtration capability.
The stock leaf spring loses tension and can lead to dirty oil blow-by.
The OEM filter bypass valve lacks any seal.
