5. Locking Gas Cap:

Selecting the Right Gas Cap

Choosing the right gas cap for your Ford Explorer involves considering a few key factors:

Vehicle Compatibility

Always check the year and model of your Ford Explorer before purchasing a gas cap. The part numbers vary depending on the specific model year and variant.
