The correct oil filter for a 2004 Chevrolet Impala with a 3800 Series II engine depends slightly on the specific engine configuration and whether the owner prefers a specific brand. However, the most commonly recommended and readily available filter is the
ACDelco PF46. This is often considered the OEM equivalent.
You can also use other filters that meet the same specifications. Always check the filter's specifications to ensure it's compatible with your vehicle before purchasing. Checking your owner's manual is always a good idea as well.
