Doc's Diesel 6.7L Powerstroke Filter Kit for Ford 2017-2025 — Fuel & Oil Filters, Water Separation

Doc's Diesel Filter Kit for 6.7L Powerstroke Ford (2017–2025) is a matched fuel and oil filter pair engineered to trap fine contaminants and separate water, keeping your engine's fuel system and oil clean between services.

This kit bundles a high-efficiency fuel filter (DFD4625) and a precision oil filter (D6128) sized specifically for 6.7L Powerstroke engines used in Ford trucks from 2017 through 2025. Each component is independently evaluated for particle capture, and the pieces are supplied together so a single purchase handles both fuel and oil filtration during routine maintenance. The design focuses on contaminant removal, water separation in the fuel system, and compatibility with manufacturer service intervals.

How does this kit protect my truck's fuel system?

The fuel filter in this kit is built to strip out dirt, rust, and debris and to separate water from diesel before contaminants reach injectors and pumps. That reduction in contaminants lowers wear on fuel system parts and helps maintain engine responsiveness under load.

• Independent testing: high particulate capture to microscopic sizes
• Water separation feature to reduce corrosion and injector issues
• Sized for direct fit on 6.7L Powerstroke Ford models (2017–2025)

What level of filtration and testing does each filter provide?

Both filters undergo independent performance evaluation and are rated to capture specific particle sizes and percentages. The oil filter targets larger contaminants common in engine oil, while the fuel filter offers fine micron-level filtration and high efficiency against small particles.

• Fuel filter rated for superior efficiency down to very small micron ranges
• Oil filter engineered for nearly complete capture of larger oil-borne particles
• Components tested independently to validate performance claims

When should I replace these filters on my Powerstroke?

Follow your vehicle manufacturer's recommended service schedule for warranty compliance; typical intervals vary by usage and fuel quality. As a practical guideline, replace fuel filters more frequently under heavy-duty or off-road use and swap oil filters at every oil change.

• Adhere to Ford service intervals for warranty requirements
• Fuel filter: commonly every 5,000–10,000 miles, up to 15,000 maximum depending on conditions
• Oil filter: change at every oil service or according to your maintenance plan

What comes in the box and is it a direct fit?

The kit ships with a matched DFD4625 fuel filter and a D6128 oil filter, selected to fit the 6.7L Powerstroke application so one order completes the standard service. Installation follows the same replacement steps as the factory parts for a straightforward swap.

• Includes one DFD4625 fuel filter and one D6128 oil filter
• Matched components eliminate compatibility guesswork
• Designed for direct replacement on 2017–2025 Ford 6.7L Powerstroke trucks

Who is this for? This filter kit is aimed at Ford 6.7L Powerstroke owners, fleet managers, and independent technicians who want a single, tested replacement set that handles both fuel and oil filtration for 2017–2025 models. If you prioritize verified filtration efficiency, water separation in diesel, and a matched pair that satisfies service requirements, this kit provides those benefits in a convenient package.
