Which Motorcraft Filter Fits My Ford Super Duty? Every OEM Part Number from the 2003 Excursion to the 2019 F550
Which Motorcraft Filter Fits My Ford Super Duty? Every OEM Part Number from the 2003 Excursion to the 2019 F550
You searched your year and model, clicked the first result, and ordered a Motorcraft fuel filter that looked right. Two days later, the filter doesn't seat properly, the housing cap won't close, and your truck cranks for 30 seconds before finally starting. Sound familiar?
Ford Powerstroke diesel engines have used four different fuel filter designs across three engine generations since 2003, and none of them are interchangeable. Ordering the FD-4617 when your 6.0L needs the FD-4616 — or grabbing an FD-4615 when your 2018 Super Duty requires the FD-4625 — doesn't just waste money. It risks air leaks, fuel contamination, and injector damage that costs thousands to repair.
This is the complete cross-reference for every Motorcraft fuel filter and oil filter that fits Ford Super Duty diesel trucks from 2003 through 2019.
What Motorcraft Fuel Filter Fits the 6.0L Powerstroke (2003–2007)?
The correct fuel filter is the Motorcraft FD-4616. The Ford part number is 3C3Z-9N184-CB.
This filter fits every 6.0L Powerstroke application: the 2003–2007 F250 Super Duty, 2003–2007 F350 Super Duty, and the 2003–2005 Ford Excursion. The FD-4616 replaced the older FD-4604 with an updated gasket design that improves sealing and prevents the air ingestion problems that plagued the original part.
The 6.0L Powerstroke is more sensitive to fuel filtration than any other Ford diesel. The high-pressure oil system (HPOP) that drives the injectors operates at up to 3,600 PSI, and even microscopic contaminants or water that passes through a substandard filter will cause injector stiction — a condition where injectors stick open or closed, creating rough idle, white smoke, and eventual injector failure. Replacing all eight injectors on a 6.0L runs $3,000 or more.
This is why the 6.0L community universally recommends genuine Motorcraft or Racor (the OEM manufacturer) filters only. Aftermarket fuel filters for this engine frequently lack the Aquabloc water-separation membrane that Motorcraft includes. Without that membrane, water reaches your injectors.
For the oil filter, the correct part is the Motorcraft FL-2016. This filter fits both the 6.0L and 6.4L engines (2003–2010). On the 6.0L specifically, a properly sealed oil filter is critical because the high-pressure oil system pressurizes through the filter housing — an aftermarket filter that's even slightly shorter can cause oil pressure delays at startup, which starves the HPOP.
If you're servicing a 2004 Excursion, a 2005 F250, or a 2006 F350 with the 6.0L, your complete ford 6.0 filter kit is the FD-4616 fuel filter paired with the FL-2016 oil filter. No other combination is correct.
What Motorcraft Fuel Filter Fits the 6.4L Powerstroke (2008–2010)?
The correct fuel filter is the Motorcraft FD-4617. The Ford part number is 8C3Z-9N184-C (also referenced as BC3Z-9N184-C). This filter replaced the original FD-4609 with an updated design.
The FD-4617 fits every 2008–2010 Ford Super Duty with the 6.4L twin-turbo Powerstroke: F250, F350, F450, and F550. The kit includes both the frame-rail-mounted primary filter and the engine-mounted secondary element.
The 6.4L runs higher fuel injection pressures than the 6.0L, making clean fuel even more critical. The oil filter for this engine is the same Motorcraft FL-2016 that covers the 6.0L — one oil filter part number spans both generations (2003–2010).
If you own a 2009 F250 or a 2010 F450, the FD-4617 and FL-2016 are your complete powerstroke maintenance kit for fuel and oil filtration.
What Motorcraft Fuel Filter Fits the 6.7L Powerstroke (2011–2016)?
The correct fuel filter is the Motorcraft FD-4615. The Ford part number is BC3Z-9N184-B.
This is the highest-volume Motorcraft diesel fuel filter sold, covering the extremely popular 2011–2016 F250, F350, F450, and F550 Super Duty trucks. The kit includes one cartridge for the frame-mounted filter and one assembly for the engine-mounted filter, plus all associated gaskets.
Ford recommends replacement every 15,000 miles or once per year. If you drive a 2012 F350, 2014 F350, or 2015 F250, this is the only fuel filter that fits correctly.
What Motorcraft Fuel Filter Fits the 6.7L Powerstroke (2017–2019)?
The correct fuel filter is the Motorcraft FD-4625, also sold as FD-4625-AA. The Ford part number is HC3Z-9N184-A.
This is a completely different design from the FD-4615 and will NOT fit 2011–2016 trucks. If you own a 2017 F350, 2018 Super Duty, or 2019 F350, the FD-4625 is your only correct option. The FD-4615 physically will not seat properly in the 2017+ housing, and forcing it risks fuel leaks and air ingestion.
Why Won't My Powerstroke Start After a Filter Change?
This is the single most common question on every Powerstroke forum, and it has two answers depending on your engine generation.
On the 6.0L and 6.4L, the fuel system is self-priming but slow. After installing the FD-4616 or FD-4617, cycle the ignition key to the ON position (without cranking) and wait 30 seconds. Repeat this 8–10 times. Each cycle runs the lift pump, pushing fuel through the new filters and purging trapped air. Attempting to start the engine before priming can introduce air into the high-pressure oil system, which creates hard-start conditions that persist for days.
On the 6.7L, the process is similar. After installing the FD-4615 or FD-4625, cycle the key to ON five to eight times, waiting 20–30 seconds between each cycle. The 6.7L is more forgiving than the 6.0L, but skipping the priming step still risks extended cranking and potential air lock in the fuel rails.
If priming doesn't resolve the no-start condition, the most likely cause is a wrong filter that isn't sealing properly — double-check your part number against this guide before troubleshooting further.
