    Nice! Congrats!

    OEM plugs are Motorcraft. If you're looking to replace them, stick with Motorcraft and stay away from Bosch in these trucks.

    Go motorcraft and don't overtorque them or they can blow out of the heads!

    But don't undertorque them either. Original plugs were ~15 lb-ft, but the new recommendation is ~28 lb-ft dry. Don't put anti-seize on the threads.
