Great OEM Replacement for 2012 V8 F150-
My truck was idling ruff & when I finally had a chance to buy these & install them? The old ones were seriously dirty & gapped between .057 to .060 which is way off from the manual that has them at .041 to .047.. I gapped them at .045 & you can even tell the truck is running while at idle because it’s so smooth now. Plus, this is a great price too. Better than any store could offer & anywhere else online? I would be afraid they would be fake, but these were genuine quality parts. Some people complained about the rear plugs on the engine being hard to reach? But I was actually very happy Ford engineers fixed that problem & left us more room than they used to leave. I remember when you would have to carefully jack up the engine itself just to be able to reach the rear plugs on some of their vehicles, and if you went too far, too hard? You could break the engine mounting bolts off. Leaving you to have to pull the whole engine, & tap those broken bolts out to remount it. Worst part of the installation was my previously injured back, & not having an Air conditioned Garage. Besides that, it was a really smooth replacement. Just had to make sure I had Motrin loaded in the Pez dispenser when I was done, with a few days off to recover.

Excellent OEM replacement for 2015 F150 5.0l 4x4
Hit 100K on my truck and figured I should replace factory plugs. Old plugs were .010-.012" worn above the recommended .051" gap. Truck runs, idles and performs much better. Hopefully I pick up a little better mpg's but we will see!

OEM plugs that work great!
These are OEM plugs so the work perfectly. Difficult to install on a 2014 F150 Lariat with the 5.0 Coyote., but that’s Ford’s design.

Factory plugs for HALF the price!!
These plugs were half the price of the ones at the local parts store, and you can't go wrong with OEM plugs. 👍

Genuine Ford Motorcraft
Look like OEM. Truck runs great. Time will tell if they last 60,000 miles again. It's a gamble...See photos of how they arrived.
