NGK Spark Plug LTR6IX-11 6509 Pack of 8

Fit my 2011 F150 5.0 just fine. Helped with fuel economy and can feel the difference in power from my old worn out plugs.

The media could not be loaded. 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!

Git theseBetter than motorcraftI’m getting 2 to 3 mpg more

I purchased a 2015 F-150 with 110,000 miles on the 5.0 Coyote engine. From the look of the spark plugs they appears to be original. Installed these and got another mile added to MPG. Ordered these from forum recommendations.

The plugs needed to be gapped prior to installation but after installation the truck ran great.

Ngk is my go-to spark plug- all my atvs and vehicles use them.Put these in a 14 F150 FX4 5.0. Saw a jump in mpgs.

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.

Quality product. Work just fine on my 2016 Ford explorer
