Key Features

• Complete kit: Includes fuel/water separator (DGF430), fuel filter (DGF401), oil filter (D5335), engine air filter (DPA6314), and cabin air filter (D3705) so owners get every routine replacement in one package.

• Measured filtration performance: Third-party testing shows the fuel/water separator and fuel filter capture 3 micron particles at high efficiency and the oil filter captures 25 micron at 99% efficiency, supporting engine protection.
• High dust capacity engine air filter: The engine air element reports 99.25% efficiency with a large dust-holding capacity, which helps maintain airflow under heavy duty conditions.

Who It's For

This kit suits owner-operators and fleet managers who service Ram 6.7L Cummins trucks themselves and want to reduce downtime and ordering complexity by buying a matched set. It is particularly useful for those who prefer matching aftermarket replacements to Mopar and popular aftermarket cross-reference numbers.

Owners who require OEM-branded packaging or who need filters outside the listed model years should look elsewhere; likewise, anyone needing specialty or heavy-duty race components beyond the stated filtration ratings should consider dedicated performance lines.
