Good spark plugs and for a good price. Also grab a gauge to properly gap!
Working well so far. Product was packaged nicely and authentically from NGK. Plugs feel sturdy, and fit in socket and were installed and torqued easily. Plugs will need to be gapped manually with a gauge.

Best plugs I’ve ever used!
These plugs are the best! I should’ve replaced them sooner. Went from 12mpg to 18mpg!

Outstanding Plug! Iridium - Finally
Finally, an Iridium plug to replace the OEM Motorcraft plug that came with my 2012 F-150 5.0. For a while you couldn't get Iridium for my truck. I tried Platinum - The performance and gas mileage was horrible. Then I tried a new NGK called Ruthenium HX - Better than Platinum but not as good as the Iridium. But now, Finally, NGK came through with an Iridium plug for the 2012 F-150 5.0, and they are as good as OEM. I was averaging 14.8... in town and lucky to get 17 -18 on the highway. Now with the new iridium,.. 16.5 in town and 20-21 on the highway. I gap mine at .049 for a hotter spark. The gap range is .049-.053. Worth every penny.

Perfect fit for my Ford
The plugs needed to be gapped prior to installation but after installation the truck ran great.

Best quality, most power and efficiency!
I replaced the original Motorcraft plugs with these high quality Iridium NGK plugs in my 2017 F150 5.0 with 76,000 miles on it. I IMMEDIATELY noticed an improvement in smoothness power the first time I hit the throttle! I checked the gap, but didn't need to adjust it thanks to great accuracy out of the box. Probably the easiest plugs to install because DOHC Ford lol! These should outlast any other options due to the Iridium's great durability!
