Doc's Diesel 6.7L Powerstroke Filter Kit — Fits Ford 2017-2025, Matched Fuel & Oil Filters

Doc's Diesel Filter Kit for Ford 6.7L Powerstroke (2017–2025) supplies a matched fuel and oil filter set engineered to capture fine particulates and separate water to protect your engine and fuel system. This matched service kit bundles the DFD4625 fuel filter and D6128 oil filter specifically engineered for 6.7L Powerstroke-equipped Ford trucks from 2017 through 2025. The components are independently tested for high contaminant removal efficiency, and the set arrives ready to replace both fuel and oil filters in one visit. Before ordering, double-check the fitment card for your truck’s year and trim to ensure exact compatibility.

How do these filters protect my Powerstroke's fuel and engine systems?

These filters work together to remove solid particulates and separate entrained water from diesel fuel while the oil filter captures wear particles and contaminants from engine oil. Removing these contaminants helps reduce component wear and keeps fuel injectors and pumps operating cleanly.

• DFD4625 fuel filter: tested 98.76% efficiency down to 3 microns.
• D6128 oil filter: tested 99% efficiency down to 25 microns.
• Water separation to reduce corrosion and injector fouling risk.
• Matched set reduces parts mismatch and simplifies servicing.

How often should I change the fuel and oil filters in my 6.7L Powerstroke?

Service intervals depend on driving conditions and manufacturer recommendations, but Doc's Diesel provides guidance to help plan maintenance. Fuel filter replacement is generally recommended more frequently in severe or off-road conditions where contamination is likely.

• Fuel filters: commonly every 5,000–10,000 miles; up to 15,000 miles in moderate conditions.
• Oil filter: change with each oil service per your vehicle’s service schedule.
• Inspect for water or heavy contamination after dusty, flooded, or long-haul work.

What comes in the Doc's Diesel filter kit and why order the matched set?

This kit ships with both the DFD4625 fuel filter and the D6128 oil filter sized for the Ford 6.7L Powerstroke application. Purchasing the matched kit ensures compatibility and saves the time of sourcing two components separately.

• Included: one DFD4625 fuel filter and one D6128 oil filter.
• Each component tested for efficiency and contaminant removal.
• One order covers the typical fuel and oil filter service for the application.
