Mopar 68677810AA Oil Filter Cartridge

2025 Plus Ram truck with the 6.7L Cummins Mopar 68677810AA Oil Filter Cartridge

The genuine OEM oil filter for the 2025 and newer Ram 6.7L inline-six Cummins turbo diesel engine carries the Mopar part number 68677810AA. Manufactured by Fleetguard Atmus Filtration, this lube filter is engineered to meet strict factory standards for filtration efficiency and durability. Whether managing a fleet or performing individual maintenance, this filter ensures your Cummins engine stays clean and operates reliably.

The Mopar 68677810AA Oil Filter Cartridge is a cartridge-style lube filter, differing from the traditional spin-on metal canister filters found on earlier 6.7L Cummins engine models. For the 2025 Ram 6.7L Cummins, this filter is positioned on the passenger side of the engine. The filter element is housed inside a casing with a top cap that requires a 28mm socket for removal during oil changes. This top-load cartridge design enhances environmental sustainability by allowing only the filter element to be replaced, simplifying and improving the cleanliness of the oil change process.

INSTALLATION:
Installing the Mopar 68677810AA oil filter on a 2025 Ram series truck with the 6.7L Cummins Turbo Diesel engine is a straightforward process, but it does require attention to detail to ensure proper sealing and performance. Here's a step-by-step guide:

To properly prepare for an engine oil and oil filter cartridge change, start by briefly running the engine to warm the oil for complete drainage. Securely elevate the vehicle using ramps or a lift, engage the parking brake, and place wheel chocks for safety. Position an oil drain pan beneath the oil pan and remove the drain plug with a socket wrench to drain the oil fully. Reinstall and torque the drain plug to the specified value. Locate the oil filter housing and use an oil filter wrench to remove the old cartridge, being prepared for any oil spills. Lightly lubricate the new filter’s O-ring with clean engine oil and ensure no old O-rings remain on the engine to prevent leaks. Hand-tighten the Mopar 68677810AA filter until the gasket contacts the base, then rotate it an additional three-quarters to one full turn without over-tightening. Refill with the correct oil type and amount, using a funnel for neat pouring. Start the engine for 30 to 60 seconds, check for leaks around the filter and drain plug, then turn off the engine and verify oil levels, topping off if needed. Dispose of used oil and the old filter responsibly at a recycling center or auto parts store. The Mopar 68677810AA includes a new O-ring—always install the new one to avoid leaks caused by worn or improperly seated seals. For the 2025+ Ram 6.7L Cummins Turbo Diesel, torque the filter using the rotation method instead of a fixed torque value: tighten by hand until the gasket contacts the surface, then rotate an additional ¾ to 1 full turn. This ensures a proper seal without over-compressing the gasket. Over-tightening can cause leaks and complicate future removal. If using a torque wrench adapter, typical torque ranges for similar filters are 18–22 lb-ft, but always prioritize the rotation method unless your service manual specifies otherwise.
