Highly recommend. 2015 Ford Focus is running much smoother with these installed. Be sure you set the gap to your specification.

I needed new spark plugs and noticed a positive difference and installing these. No problems with them and the box came sealed.

It seems to be of good quality for what I paid for it should be is double iridium.So I i am going to be placing these in my vehicle in the next few days.I meant to do it last week, but I wasn't feeling well. I am a woman, by the way, I am early middle-aged and yes, I do know how to fix quite a bit on my vehicle myself, which saves me money. And I'm going to see how well these work. They have good reviews and it's long overdue time for me to tune up my vehicle. So I will leave a second update sometime. Next week, probably because it won't stop raining where I'm at until then, and I don't have a very large garage to work in. So I kind of have to go outside to do most of this, but I will let you know how it goes :)

I installed these in a 3.5L Ford Ecoboost engine. The plugs were gapped at 0.032 out of the box, and I checked each one. I replaced the rubber boots on the ignition coils and have had no issues. Prior to replacement, I noticed an engine misfire under heavy acceleration, but I have not experienced any issues since replacing the plugs.
It's all good

I installed these in my 2012 Ford Focus SE and they fit perfectly. They are quality and you can see that when you unbox them. After installing them I immediately noticed a difference in performance of the engine. It revved up easier and the engine just wanted to keep on revving. Should notice better gas mileage soon. Great plugs. Hope this helps. Cheers

These are exactly what I expected. Time will tell if they work and last as long as they say.

The wrong part was listed for a 2011 Ford Focus SES 2.0 liter engine spark plug. Correct part number is 9655 not 9697.

I replaced the plugs and the coils on my 2016 Expedition. These were a perfect fit, with no adjustments needed. After driving around for a day, the engine runs great with no more check engine light due to a misfire. Only thing that could be better is if these came in a 6-pack

Works for 2015 ford transit 3.5L Ecoboost. Default gap works for my vehicle, no re-gap required. Replaced all 6 plugs and fuel efficiency greatly improved. Van runs and accelerates much smoother. Worth the money!
