The PF63 engine oil filter (Fig. 5) is the new recommended filter specification for 2020-2023 Silverado 2500HD/3500HD, Sierra 2500HD/3500HD, Express, Savana; and 2019-2023 Silverado 4500/5500/6500 models equipped with the 6.6L Duramax diesel engine (RPO L5P, L5D).

The PF63 engine oil filter will be the factory-installed filter for applicable 2023 models equipped with the 6.6L Duramax diesel engine (RPO L5P). The current PF26 engine oil filter also is compatible with these diesel engines. (Fig. 6)

The PF63 filter is 3/4 inches (19 mm) narrower than the PF26 filter, but it has a taller pleat height, which maximizes volume efficiency and cold flow performance. (Fig. 7)
