    So any answer you get here will also be "on the internet" right? Did you check your Owner's Manual?

  • I'd think the NGK site would be authoritative. ngk.com/product.aspx?zpid=40122

RockAuto.com shows the gap for the two different NGK Iridium plugs listed (95853 & 6509) for your F-150 5.0 to be 0.052".

With that in mind, most plugs of this type are set from the factory. They'll usually state "Do Not Gap" on the box. Ensure you check to see if this is true with your plugs before you start bending on things.
