Coil packs and spark plugs
 

Has anyone upgraded their coil packs and spark plugs on their F150 coyote engine? Had issues throwing a code when I leaned on it. Ford dealer said I needed new sparks plugs which only had 15,000 miles on them. I figured it was a coil pack. I did mine and installed M-12029-M52 which I had to do a minor modification. Seems to be a good upgrade.
