5 star tuning recommended re setting the plug gap to .030 so I ordered new autolites that said they were gapped at .031 I checked the old plugs also .031 .but I was pleased the plugs looked perfect at 20 k miles. Just thought you guys with 2018 expiditions with tuners would like to know.apparently the gap has been tightened up by ford.
Also, the guys and gals at 5 star are the absolute best people to work with.they sell a quality product and stand behind it.
