The correct oil filter for this truck is Motorcraft FL-820-S. This OEM filter is widely cited as the appropriate choice for the 5.4-liter V8 in 2001 F-150 models, and many aftermarket brands offer cross-references with the same specifications.
Overview of compatibility
The 2001 F-150 with a 5.4L modular V8 uses a standard spin-on oil filter with Ford's threading and gasket size. While a given engine can vary by trim and build, the FL-820-S is the default recommended filter; if you replace with an aftermarket part, ensure the filter matches the same thread size, gasket, and overall dimensions.
Below are common replacement options that fit the engine and are widely used by owners and mechanics.
- Motorcraft FL-820-S (OEM Ford filter)
- Wix equivalent to FL-820-S
- Bosch equivalent to FL-820-S
- Purolator equivalent to FL-820-S
Using a filter that matches FL-820-S specifications ensures proper sealing, filtration capacity, and compatibility with the 5.4L engine.
How to verify the correct filter for your vehicle
To confirm compatibility, check the owner's manual, inspect the filter currently installed for the part number, or consult a Ford dealer or trusted parts retailer. You can also use the VIN and filter reference charts from brands to find cross-references that match the FL-820-S specifications.
Summary
For a 2001 Ford F-150 with the 5.4L engine, the recommended oil filter is Motorcraft FL-820-S. Aftermarket cross-references from Wix, Bosch, and Purolator typically exist, but always verify the part matches the same thread size, gasket diameter, and mounting configuration as the OEM filter.
