The Ford F-150 with a 5.4-liter Triton V8 uses the Motorcraft FL820S oil filter as the standard replacement. This is the OEM specification and is widely available from aftermarket brands as well.
Model coverage and fitment
The 5.4L Triton engine, used across various F-150 years and configurations, relies on a canister-style oil filter with the same basic mounting and dimensions. For most model years that used the 5.4L Triton, the FL820S is the factory-recommended filter. When shopping aftermarket, you’ll often see FL820S-listed equivalents, which are designed to match the same thread size, gasket, and overall dimensions.
Notes on compatibility and cross-referencing
If you prefer an aftermarket option, many brands list FL820S compatibility or provide a cross-reference to Motorcraft FL820S on the packaging. Always verify the fitment for your specific year and engine variant (two-valve vs. three-valve) by checking the product details or using a retailer’s vehicle fitment tool.
Recommended filter options
Use this as a quick reference for the primary choice, with the understanding that cross-reference options exist from other brands.
- Motorcraft FL820S
While some brands market FL820S-equivalents (often via cross-reference listings to the Motorcraft part), confirm compatibility for your exact F-150 year and 5.4L Triton variant before purchasing.
How to confirm fitment for your truck
Consult the owner's manual or under-hood labeling for the recommended filter part number. If replacing an older filter, compare the filter’s overall height, thread size, and canister diameter to ensure the aftermarket part matches OEM specifications. Many retailers offer tools where you can input your year, make, model, and engine to verify compatibility.
Summary
For a Ford F-150 with a 5.4L Triton, the OEM oil filter is Motorcraft FL820S. When shopping aftermarket, look for FL820S-compatible filters and always double-check fitment for your specific year and engine variant to ensure proper filtration and oil pressure.
