    • Great performance. Great gas mileage.
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.

    • 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. ... show more

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

    • Work well!
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.

    • Nice quality, fit and finish on my 2012 Honda Civic.
These plugs appear to work just fine but I only had them in the car for a month. It takes about 20 minutes to install on a 2012 Honda Civic 1.8 engine.

    • Great value plugs
Great value vs oem motorcraft plugs. Changed these over 25,000 miles ago and still running and slightly better gas mileage than motorcraft plugs.
