Stop the debris before it reaches your CP4. Your 6.7L Cummins is a powerhouse, but its fuel system is highly sensitive to even the smallest particulates. The Genuine Mopar 68065608AA (MO-608) is the engine-mounted NanoNet® filter designed to provide a 2-micron barrier of protection. Don't let a "cheap" alternative be the reason you're replacing high-pressure injectors.
🧠 WHY THIS MATTERS
At Valtrix Powertrain, we understand that diesel filtration is about more than just "fitting" in the housing. The MO-608 utilizes specialized synthetic media that maintains high flow rates even as it captures extreme levels of contaminants. This filter is essential for maintaining the correct fuel rail pressure required for optimal combustion. Without it, you risk premature wear on the high-pressure pump and reduced engine life.

❓ FAQ
Q: Is the MO-608 the same as the MO-291?
A: They are very similar and often used interchangeably in the same 2013+ housings, but always refer to your owner's manual or VIN. Both provide high-efficiency NanoNet® filtration for the 6.7L Cummins.
Q: Does this filter catch water?
A: While this filter has some water-stripping capability, its primary job is particulate filtration. The frame-mounted separator (like the MO-631 or 68197867AB) is responsible for the bulk of water removal.
Q: Where is this filter located?
A: On the 6.7L Cummins, this is located in the fuel filter canister on the driver's side of the engine block, accessible from under the hood.
