The Ram 1500 with a 5.7 Hemi uses a standard 3/4-16 threaded oil filter. The OEM Mopar replacement is commonly listed for this engine as 05019957AA, and many aftermarket filters cross-reference to this size and mounting. Always verify with your VIN or by inspecting the filter you remove to ensure the correct fit.
For 2005 production specifically, the exact filter model can vary by build date and regional availability. If you’re unsure, check the existing filter for thread size and length, consult the owner’s manual or a dealer parts fiche using your VIN, or rely on a cross-reference from a reputable filter maker. In practice, most major brands offer filters that match the same 3/4-16 thread and similar length, which will fit the 5.7L Hemi in this truck.
Filter options for the 5.7 Hemi
Here are common options known to fit the 5.7 Hemi in the 2005 Ram, all sharing the same 3/4-16 thread. Use the packaging or a cross-reference chart to confirm compatibility with your exact vehicle.
- Mopar OEM oil filter (official replacement for the 5.7 Hemi; verify part number with your VIN).
- Major aftermarket filters from brands such as Wix, Purolator, Bosch, Fram, and Motorcraft that specify a 3/4-16 thread and an appropriate length for the 5.7L Hemi engines.
These options cover the typical cross-reference landscape for this engine. Always double-check against your vehicle’s VIN or the specific filter you’re replacing to ensure a perfect match.
How to verify and install the filter
To ensure you select the correct filter and install it properly, follow these steps:
- Inspect the filter you plan to replace to confirm the thread size (3/4-16) and approximate length matches your vehicle’s current filter.
- Consult the owner’s manual or a dealer parts database using your VIN to confirm the exact Mopar replacement number for your truck.
- If using an aftermarket filter, check the packaging for 3/4-16 thread compatibility and compare the filter’s length and micron rating to the OEM specifications.
- When installing, lubricate the gasket with a little clean oil, thread the filter by hand to avoid cross-threading, and tighten to the manufacturer’s recommended torque (generally hand-tight plus a quick quarter-turn; consult your service manual).
After installation, refill as needed, run the engine to check for leaks, and reset the oil-life monitor if equipped.
