1. Why OEM Filters Matter: Mopar Quality Assurance

Genuine Fit, Form & Function

  • These Mopar filters are designed specifically for the 6.7L Cummins, delivering perfect compatibility and sealing .

  • Built to the same OEM specs, they ensure reliability that aftermarket or knockoffs often lack .

Protects High‑Pressure Fuel System

  • Includes genuine oil filter (05083285AA equivalent), designed for heavy-duty operation .

3. Replacement Intervals: Timing Matters
