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.

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.

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

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