2012 F-150 eco boost, just bought a used one. Running rough so went to a forum and found plugs seem to burn out early. 90,000 miles on mine and so bought these plugs for 2013 and was a very easy job installing!!! Truck now purrs. idle around 8-900 rps, excels very well, glad I did this. My plan is to replace every 50,000, worth it for the 30 minute in stall.

Need exact product to keep Ford Warranty intact !! Motorcraft spark plugs are made by Autolite, BUT they are made to Ford's specifications NOT Autolites. Buy Motorcraft if for your Ford vehicle. I found prices online to be about 1/2 the price at a Ford Dealership !! Easy to replace. BUT double check the spark plug gap !! Make sure the gap meets the specification for your Ford vehicle.

Got brand new plugs for my 2014 f150 3.5 Ecoboost. Gap was set properly for my engine. Plugs were in original packaging with plastic protector around threads. Would definitely buy again!

Made my truck run like brand new no more turbo lag along with rough idle when cold. I wish I change mine awhile ago as I've notice a gain in fuel efficiency. I'll be back for more in another 50k if you have them still 😀
