Doc's Diesel 6.4L Powerstroke Filter Kit — 2008–2010 Fuel/Water Separator & Oil Filter, OEM-Grade

Doc's Diesel 6.4L Powerstroke Filter Kit replaces Motorcraft FD4617 and FL2016 with OEM-grade fuel/water separator and oil filter performance for 2008–2010 Ford 6.4L trucks.

Built by a Midwest independent filter maker, this kit brings a complete fuel and oil filtration solution for Ford 6.4L Powerstroke engines from model years 2008–2010. The set pairs an engineered fuel/water separator with a high-efficiency oil filter, both designed to match the original equipment’s form, fit, and flow while using premium media aimed at trapping contaminants and protecting downstream components.

How does this kit protect my 6.4L Powerstroke on tough roads?

The fuel/water separator removes free water and filters particulate before fuel reaches injectors, while the oil filter captures contaminants generated by engine wear and combustion. Using multi-layer media mimicking OEM specifications helps keep fuel and oil systems cleaner, supporting consistent performance under load.

• Fuel filter replaces Motorcraft FD4617 and Wix 33963 equivalents for correct fitment.
• Oil filter replaces Motorcraft FL2016 and Wix 57312 equivalents to maintain oil flow and filtration area.
• Premium three-layer media in fuel filter to separate water and trap particulates.
• Designed to meet or exceed OE filtration efficiency and pressure tolerances.

What are the specific parts included and interchange notes?

This kit includes one fuel/water separator and one spin-on oil filter tailored for the 2008–2010 6.4L Powerstroke. Doc’s Diesel lists cross-references to common OEM and aftermarket part numbers so you can verify compatibility before installation.

How long will these filters last and when should I change them?

Service intervals follow vehicle manufacturer guidelines and operating conditions—Doc’s Diesel filters are intended to perform at OE levels, but replacement frequency depends on mileage, driving environment, and fuel quality. Inspect fuel system and oil condition regularly and change filters at scheduled maintenance or sooner if contamination is suspected.

• Follow Ford’s recommended intervals for oil and fuel filter changes as a starting point.
• Severe duty, dirty fuel, or heavy towing may require more frequent replacement.
• Replace immediately if you notice fuel system issues, water in fuel, or oil contamination.
