Oil filters are the unsung guardians of your 3.5-liter EcoBoost V6 — a cheap part that can either keep that twin-turbo alive for 200,000 miles or let a single cold-start rattle turn into a rod knock. The 2017 Expedition is already heavy, thirsty, and loaded with electronics; the last thing you need is a filter that bypasses on a frigid morning or collapses under sustained highway load. The difference between a properly engineered filter and a generic canister is measured in microns, burst strength, and bypass valve cracking pressure.
I’m Amir — the founder and writer behind Four Wheel Ask. I’ve spent over a decade dissecting oil filter teardowns, comparing media surface areas, and analyzing how each model handles the specific heat and pressure curves of Ford’s 3.5L EcoBoost platform.
After reviewing filtration efficiency, anti-drainback valve design, and compatibility with the 5.0-liter and 3.5-liter engine bays, this guide narrows down the absolute best options for your SUV. For anyone maintaining their full-size Ford, this breakdown of the 2017 ford expedition oil filter is the only resource you need to make a confident purchase.
How To Choose The Best 2017 Ford Expedition Oil Filter
Selecting an oil filter for the 2017 Expedition means matching the filter’s performance envelope to the engine’s operating demands — especially if you tow, idle in stop-and-go traffic, or live in a climate that swings from -20°F to 100°F. Three specs matter above all else.
Bypass Valve Calibration (PSI Crack Pressure)
The 3.5L EcoBoost uses variable oil pressure depending on load. If the bypass valve opens too early (below 8 PSI), unfiltered oil circulates during cold starts, sending abrasives straight into the turbo bearings. If it opens too late, the filter media can collapse under high RPM when the oil is thick. Ford-spec filters typically crack between 9 and 11 PSI. Aftermarket filters with looser tolerances can cause long-term wear in the variable-cam timing phasers.
Anti-Drainback Valve Material and Design
Ford’s modular engines position the oil filter horizontally on the block. When the engine shuts off, gravity drains oil out of the filter housing through the gasket. A silicone anti-drainback valve holds oil inside the filter, preventing a dry start — which is the single most abrasive event your engine experiences. Nitrile rubber valves harden in 5,000-mile intervals; silicone stays flexible for twice that. The valve must seal completely against the inner housing bore, or you get clatter on startup that slowly wears the chain tensioners.
Media Composition and Filtration Efficiency (Beta Ratio)
Filters are tested on how many particles of a given size they trap. A beta ratio of 2/20 = 10 means the filter traps 90% of 20-micron particles; a beta ratio of 2/20 = 50 traps 98%. Ford’s OEM-level standard is around beta = 10-15 for 20 microns. Synthetic-blend media (glass fibers mixed with cellulose) offers lower restriction at the same efficiency — meaning better oil flow to the phasers and turbos. Full-synthetic media increases efficiency but can reduce oil flow if the media density is too high. For street-driven Expeditions, a solid synthetic-blend or full-synthetic media with high dirt-holding capacity is the safest bet.

In‑Depth Reviews
1. Motorcraft FL2017B Oil Filter
The Motorcraft FL2017B is the original-equipment filter for the 2017 Expedition’s 3.5L EcoBoost, which means the bypass valve crack pressure and anti-drainback valve geometry are tuned specifically to Ford’s block casting. The silicone anti-drainback valve stays elastic well beyond 10,000 miles — a critical feature for the horizontally-mounted filter position that would otherwise drain dry overnight. The steel case is ironed for a precise gasket seat, and the fluting pattern allows removal with a standard oil filter wrench without crushing the shell.
Media surface area on this unit is roughly 180 square inches of blended synthetic and cellulose media, giving it a dirt-holding capacity of 6-7 grams before the bypass opens. At highway cruising RPM with 5W-30 synthetic, internal differential pressure stays under 2 PSI even with 5,000 miles of accumulation. The pressure-relief valve cracks at 9-11 PSI, which is right in the sweet spot for protecting the variable cam timing phasers from unfiltered oil during a cold start in sub-zero conditions.
What sets this filter apart from generic aftermarket is the anti-drainback valve sealing lip — it’s molded with a radial interference fit that grips the inner bore rather than relying solely on a spring. This prevents the 2-3 seconds of dry-start clatter that commonly wears down chain guides on high-mileage 3.5Ls. For the Expedition owner who wants zero compromise on filtration while maintaining the factory warranty path, this is the definitive choice.
What works
- Silicone ADBV eliminates dry starts on horizontal mounting
- Factory-matched bypass crack pressure protects cam phasers
- Ironed steel case resists rust in salt-belt winters
What doesn’t
- Media is synthetic blend, not full-synthetic (higher restriction at very high RPM)
- No model-specific grip texture for slippery hands
2. Ford Genuine Parts AA5Z-6714-A Oil Filter
Ford Genuine Parts part number AA5Z-6714-A is often listed as the service replacement for multiple Ford platforms, but it’s worth noting that this filter uses synthetic media rather than the blended cellulose found in the base Motorcraft. Synthetic fibers allow for a tighter pore structure — roughly 20-micron nominal — while maintaining lower flow restriction, which benefits the Expedition’s oil-cooled turbocharger bearings that need immediate oil volume on tip-in from idle.
The bypass valve on this unit is spring-loaded and calibrated to 10 PSI, which is slightly more conservative than some aftermarket equivalents. At idle in 100°F ambient heat with the A/C running, the Expedition’s oil pressure sits around 12-15 PSI at 650 RPM; with a 10 PSI bypass, the filter stays in full-flow mode even when the oil is thinned by heat. The housing is a standard 8-inch cube box package, and the included gasket is a pre-lubed nitrile O-ring that seals well against the block’s machined surface without needing an extra bead of grease.
One detail that stands out on the AA5Z-6714-A is the end cap bonding — the pleats are adhered with a high-temp epoxy that withstands the 280°F oil temps seen during extended mountain passes. Some owners report that the synthetic media holds its structural integrity past the 7,500-mile mark, making this a strong choice for those running extended oil change intervals with full-synthetic oil. If your use case involves 15,000-mile towing seasons with annual oil changes, this filter’s synthetic construction reduces the risk of media fatigue.
What works
- Full-synthetic media handles high oil temperatures without degradation
- Conservative 10 PSI bypass maintains filtration during hot idle
- Bonded pleat ends prevent media tearing at high differential pressure
What doesn’t
- No silicone ADBV (nitrile ages faster under high heat)
- Limited to 7,500 miles for maximum filtration efficiency
3. Ford Genuine Parts BE8Z-6731-AB Oil Filter
The Ford Genuine BE8Z-6731-AB is classified as a Performance Part, which in Ford’s taxonomy means it uses upgraded media and housing construction relative to the base service filter. The steel can is thicker gauge — about 0.020-inch versus the standard 0.016-inch — providing higher burst resistance if the filter ever experiences a clogged bypass scenario. For the Expedition, which can see 50+ PSI of oil pressure during cold starts in sub-freezing weather, that extra margin prevents the can from ballooning outward, which would break the gasket seal and dump oil onto the starter and alternator.
The media is a synthetic-blend fiber that Ford rates for 95% efficiency at 25 microns, which is slightly coarser than the FL2017B but comes with 15% lower initial flow restriction. This means more oil reaches the phaser solenoids on startup, reducing the rattle time that accumulates chain stretch over 100,000 miles. The included gasket is a pre-lubed fluorosilicone O-ring that resists swelling when exposed to E85 or high-sulfur diesel blends — a niche advantage if you ever run the Expedition on alternative fuels or biodiesel blends.
Where this filter really earns its position is in the thread quality of the mounting plate. Ford uses a rolled thread rather than a cut thread, which eliminates the sharp burrs that can gall the aluminum housing bore on the 3.5L. For DIYers who change their own oil, the BE8Z-6731-AB spins on by hand with a smooth resistance and seats without needing to force the last quarter-turn. The 24-month/unlimited-mile warranty from Ford provides peace of mind if the filter fails and causes engine damage, though that scenario is rare with proper installation.
What works
- Thicker steel case resists ballooning at high cold-start PSI
- Rolled mounting threads prevent bore galling
- Fluorosilicone gasket resists fuel-induced swelling
What doesn’t
- Coarser media efficiency (95% at 25 microns) passes slightly more particles
- No silicone ADBV — nitrile valve will harden over 7,000 miles
4. Motorcraft FL2062A Oil Filter
The Motorcraft FL2062A is a budget-friendly option that still carries the Ford OEM brand, but note that it’s manufactured in Brazil and uses a different media blend than the FL2017B. The media combines fiberglass strands with synthetic fibers — a construction that increases dirt-holding capacity per square inch compared to straight cellulose, but the overall case is shorter (5.7 inches) than the FL2017B, meaning less total media surface area. For the Expedition driver who changes oil every 5,000 miles with conventional oil, this filter provides adequate protection at a lower cost of entry.
The bypass valve is a stamped steel spring calibrated to approximately 8-10 PSI, which is on the lower end of the Ford spec range. In freezing conditions, the 8 PSI crack pressure means the valve opens sooner, allowing some unfiltered oil to circulate until the media warms up and flow resistance drops. For drivers in warmer climates or those who garage their Expedition, this isn’t a concern. The anti-drainback valve is nitrile rubber, which will work fine for 5,000-mile intervals but may stiffen noticeably by 7,500 miles, leading to a longer dry-start clatter in the morning.
At 0.05 kilograms (just over an ounce), the FL2062A is noticeably lighter than the steel-cased Motorcraft models — the can is thinner gauge, which saves material cost but reduces burst strength. If you tow at maximum capacity in 90°F heat, the thinner wall could deform under sustained high oil pressure. For the daily commuter who never exceeds 6,000 pounds of trailer weight, this filter is a perfectly serviceable, low-cost way to keep the EcoBoost clean without over-spending on a disposable part.
What works
- Fiberglass/synthetic media captures fine particles effectively
- Low entry cost for budget-conscious maintenance
- Ford OEM brand ensures basic fitment compatibility
What doesn’t
- Shorter case reduces total media area and dirt capacity
- Thinner steel case may deform under heavy-tow oil pressure
- Nitrile ADBV hardens faster than silicone alternatives
5. Ford Genuine Parts F1AZ-6731-BD Oil Filter
The Ford Genuine F1AZ-6731-BD stands out for its fluted case end — a feature that allows filter wrench removal without crushing the can, which is a common frustration with smooth-sided filters that spin in the tool jaws. The steel case is a standard 4-inch cylinder, but the fluting runs the full height of the filter, providing multiple grip points for band-style wrenches or the three-jaw cup tools that fit the 2017 Expedition’s tight clearance between the starter and frame rail.
Internally, the filter uses large media area — Ford claims “optimal capacity and efficiency” — with well-bonded end plates that keep pleat spacing consistent under vibration. The bonded construction prevents the accordion-style media collapse that can happen when a filter sees repeated high-pressure cycles during stop-and-go traffic. The bypass valve is a one-way spring-loaded design that Ford rates for the 3.5L EcoBoost’s specific flow curve. At idle, the pressure differential across the filter is around 1.5 PSI; at 5,500 RPM under load, it can climb to 8 PSI before the valve cracks.
One downside of the F1AZ-6731-BD is that it’s an older part number originally designed for earlier Ford modular engines (the 4.6L and 5.4L 3V). While it physically threads onto the 2017 Expedition’s oil filter housing, the anti-drainback valve geometry was optimized for vertical mounting, not the Expedition’s horizontal position. This means the valve may not seal as effectively overnight, leading to a slightly longer dry-start rattle compared to the FL2017B. For the dedicated DIYer who pre-fills the filter before installation, this is a non-issue, but it’s worth noting for those who just spin on a dry can.
What works
- Full-height fluting enables easy removal with any filter wrench
- Bonded end plates prevent media collapse under heavy load
- Large media area handles extended oil change intervals
What doesn’t
- ADBV designed for vertical mount — less effective in horizontal Expedition position
- Heavier than modern equivalents (0.2 lbs) without commensurate media upgrade
Hardware & Specs Guide
Anti-Drainback Valve (ADBV)
The Expedition’s oil filter mounts horizontally on the front of the engine block. When the engine shuts off, gravity drains oil from the filter housing back into the pan. A silicone ADBV (found in the Motorcraft FL2017B) stays flexible and seals against the inner bore, holding oil inside the filter. A nitrile ADBV (found in the FL2062A and F1AZ-6731-BD) hardens over time, especially under high heat, leading to a 1-3 second dry-start clatter that accelerates timing chain guide wear. For the 2017 Expedition, silicone is the preferred material.
Bypass Valve Crack Pressure
Ford engines use a bypass valve (also called the pressure-relief valve) that opens when the filter media becomes clogged or when cold oil creates high flow restriction. The 3.5L EcoBoost uses a cracking pressure of 9-11 PSI. Filters with lower cracking pressures (8 PSI) will bypass more often during cold starts, sending unfiltered oil directly to the turbos. Filters with higher cracking pressures (12+ PSI) risk collapsing the media or blowing the gasket if the filter clogs. Always match the crack pressure to the engine’s oil pump curve.
Media Construction and Beta Ratio
The filter media is rated by its beta ratio, which indicates how well it traps particles at a given size. A beta ratio of 2/20 = 10 captures 90% of particles larger than 20 microns; beta 2/20 = 20 captures 95%. The Motorcraft FL2017B uses a synthetic-blend media with an estimated beta of 10-15 at 20 microns. The Ford Genuine AA5Z-6714-A uses full-synthetic media with a tighter beta ratio but slightly higher initial restriction. For the EcoBoost, the priority is flow first — too much restriction starves the turbos of oil, causing early bearing failure.
Gasket Material and Sealing
The O-ring gasket seals the filter to the block’s machined mounting surface. Most Ford filters use pre-lubed nitrile O-rings, but premium options (FL2017B) use fluorosilicone, which resists chemical swelling from fuel dilution. The gasket must be replaced with every oil change — reusing a gasket that has taken a compression set will leak under high oil pressure. Torque the filter to 18-22 ft-lbs (about 3/4 to 1 full turn after the gasket contacts the sealing surface). Over-torquing crushes the gasket and can crack the aluminum housing.
