Doc's Auto Parts Diesel Filter Set for Ford 6.7L Powerstroke (2011–2016) — 3‑Piece High‑Efficiency Kit

Doc's Diesel Filter Set for Ford 6.7L Powerstroke (2011–2016) combines a high-efficiency fuel filter, oil filter, and engine air filter to service F-250/F-350/F-450/F-550 trucks in one matched kit.

This three-piece maintenance kit is engineered to match the factory fit for 6.7L Powerstroke engines used in Ford trucks from 2011 through 2016. Each filter has been independently evaluated for particle removal and is selected so a single purchase covers the most common routine service needs — fuel, engine oil, and intake air. The components are built to trap contaminants, separate water from diesel, and keep airflow clean, helping preserve injector and turbocharger longevity when changed at recommended intervals.

How does the fuel filter protect my 6.7L Powerstroke?

The DFD4615 fuel filter captures dirt and separates free water from diesel before it reaches high-pressure pump and injectors. Independent testing rated it at 96.92% efficiency down to 3 microns, meaning it removes very small particles that can accelerate wear.

• Water separation to reduce corrosion and injector damage
• 96.92% efficiency at 3 microns per independent testing
• Direct-fit for Ford 6.7L Powerstroke 2011–2016, simplifying installation

What performance can I expect from the oil and air filters?

The D6128 oil filter and DPA6109 air filter are chosen to meet high filtration standards: the oil filter removes 99% of particles down to 25 microns, while the air filter exceeds 99% efficiency and captures fine dust particles that reduce engine life and efficiency.

• D6128 oil filter: 99% efficiency at 25 microns to protect bearings and rings
• DPA6109 air filter: 99.25% efficiency with tested dust-holding capacity for longer service intervals
• All pieces matched to the same vehicle application for consistent protection

How often should I change these filters on my truck?

Service intervals vary by driving conditions and manufacturer guidance; follow your Ford maintenance schedule for warranty compliance. As a practical guideline, fuel filters are often changed every 5,000–10,000 miles and up to 15,000 miles maximum under normal conditions, while oil and air changes depend on mileage and operating environment.

• Follow vehicle owner’s manual for official intervals
• Fuel filter: commonly 5,000–10,000 miles; 15,000 miles maximum advised
• Oil and air: adjust based on towing, diesel quality, and dusty environments
