There isn’t a single universal oil filter number for every 6.7-liter Ram truck; the correct part depends on the model year and the filter brand you choose.
The Ram 2500 and 3500 equipped with the 6.7-liter Cummins turbo diesel have seen various oil filter designs and cross-reference mappings over the years. Because the exact part number can change with updates to the engine, emissions equipment, or filter manufacturer, identifying the right filter requires checking your specific vehicle details and, if needed, confirming with a parts professional. This article explains how to pinpoint the correct oil filter PN for a 6.7L Ram and what options are available from OEM and aftermarket suppliers.
Why the number varies by year and setup
Different model years and configurations of the 6.7L Cummins in Ram trucks have used slightly different oil filters or filter assemblies. Variations can arise from changes in thread size, gasket design, filter height, or the choice between OEM (Mopar) and aftermarket brands. Even within the same engine family, updates to emissions controls or accessories can necessitate a different PN. Because of these factors, the exact part number isn’t universal across all 6.7L Rams.
Below are the primary factors that determine the exact oil filter part number for a 6.7L Ram.
- Model year and revision of the 6.7L Cummins engine
- Filter brand type (OEM Mopar vs aftermarket such as Wix, Baldwin, Fleetguard, or Donaldson)
- Vehicle configuration (Ram 2500 vs Ram 3500; presence of emission controls or engine updates)
- Regional availability and production run (parts can differ by market or supplier)
Because these factors can alter the PN, always verify against your specific truck’s details rather than assuming a single number applies to every 6.7L Ram.
How to find the exact oil filter number for your Ram 6.7
To accurately identify the right oil filter PN for your truck, follow these steps to verify against your vehicle’s details and current filter.
- Check the owner’s manual or service manual for the recommended oil filter PN for your engine and year.
- Inspect the currently installed oil filter: read any stamping or labeling on the filter can or cap to capture the brand and part number.
- Use your VIN to look up parts online. Enter the VIN on the official Mopar Parts site or a reputable parts retailer to pull the exact filter PN and cross-reference options for your vehicle.
- Ask a dealership or trusted parts counter with your year, model, and VIN to confirm the correct PN and any compatible cross-references.
- When purchasing, bring the old filter or its packaging to ensure you’re matching thread size, gasket style, and overall dimensions.
Following these steps helps ensure you purchase the correct filter for your specific Ram 6.7 and avoid compatibility issues.
Brand-specific cross-reference options
Many buyers prefer aftermarket alternatives to the OEM Mopar filter. Below are general guidance points for cross-referencing across common brands; always confirm with the retailer using your VIN.
- Mopar (OEM): The official Ram/Mopar filter is designed to fit your engine’s exact specifications and is usually the safest choice for warranty and longevity.
- Wix, Baldwin, Fleetguard: These brands offer compatible filters that cross-reference to the OEM part, but verify the exact PN via VIN lookup or cross-reference charts.
- Other reputable brands (e.g., Donaldson, Motorcraft): These can be compatible alternatives; use cross-reference tools or retailer associates to confirm fitment for your 6.7L Ram.
When selecting an aftermarket option, ensure the chosen filter is specified for a 6.7L Cummins and matches thread size, seal type, and overall dimensions required by your truck’s oil system.
Practical tips for reliability
Always cross-check using your exact vehicle details. Even small changes in year or regional spec can alter compatibility. If in doubt, default to the OEM Mopar part or have a parts professional confirm cross-references with your VIN.
Summary
The oil filter number for a 6.7 Dodge Ram is not universal; it depends on the engine year, configuration, and whether you choose OEM or aftermarket filters. To identify the correct PN, consult the owner’s manual, inspect the current filter, and use your VIN to verify cross-references with Mopar or reputable aftermarket brands. By confirming these details, you ensure the right filter is used for your Ram 2500 or 3500 with the 6.7L Cummins engine.
