2024 Ford F-150 spark plug gaps vary by engine.
What spark plug gap does a 2024 Ford F-150 need?
The 2024 US manual lists 0.028–0.031 inches for the standard 2.7L and 3.5L EcoBoost engines, but 0.039–0.043 inches for the 5.0L V8. Identify the engine before ordering or fitting plugs.
Applicable to: US-market 2024 F-150 gasoline engines; the 3.5L row excludes Raptor and is not a hybrid-specific row.

Match the exact vehicle.
Check 1
Find the actual engine from the vehicle documentation; F-150 is a model name, not an engine or spark-plug specification.
Check 2
These are original factory-reference gap ranges, not instructions to bend the electrodes on a particular replacement plug. Check the specified replacement part and service instructions.
Check 3
Do not apply the non-Raptor 3.5L row to the Raptor, hybrid PowerBoost, 5.2L or other model years without checking their own Ford sections.
