The recommended oil filter for a 2004 Dodge Ram with a 5.7-liter Hemi is Mopar’s canister filter MS-6393, which is the PH8A-type filter. This is the standard fit for most early 2000s 5.7 Hemi Rams.
In practice, the 2004 Ram 5.7 Hemi uses a screw-on canister filter with a 3/4-16 thread. While many third-party brands offer PH8A-equivalent filters, Mopar MS-6393 remains the most reliable choice for a perfect match to the engine and oil system in that year, unless your vehicle has a unusual build or aftermarket setup. Always verify with your VIN if you’re unsure.
