No problem with plugs I have used them before and they are great however.AMAZON: THESE ARE SENSITIVE PARTS THEY CANNOT BE SHIPPED AS THEY WERE IN THE PICTURE! Literally, I opened the box and that is what I saw.If you buy spark plugs off Amazon first checked to see if they were used, packaged correctly, and if they had been opened before what they sent me had clearly been opened before and was missing the protective cardboard that protects the electrode. You should always check the spark gap.

Use them for stage 3 focus st. Eats through any plug after about 10-15k if you are hard on them.

These worked fine for a coyote 5.0 with a blower. Gaps were all over the place, so be sure and gap them yourself. One plug had fallen out of its individual carton inside of the amazon package, so perhaps the shipper could do better.

Overall very happy with the purchase. Used in my 2013 Mustang GT. Saw a 1.8mpg gain overall using .51 gap.One of the plugs was loos in packaging but did not suffer any damage.

Great plugs, and sworn by my tuner over the Denso ITV22 equivalent (he's had too many of those drop bits into the combustion chamber and said NEVER to use them, always these). My Speed 3 loves them at fully bolted, E25 mix, methanol spraying, and a BNR S3 putting down 390/385 at the wheels.Caution: there IS NO one-size-fits-all heat range. Learn to read your plugs. My Speed loves step-colders. I tried normal heat range because lots of folks were suggesting step-colders weren't necessary. After running them a while I pulled them and it was clear by the black speckling on the ceramic that my car wants 1 step colders (these). Don't go by a dogmatic approach. Go by reading your actual plugs on your actual car.Based on plug reading, these are the ones for me, gapped initially to 0.026" and closed back down to that gap several times before I run a new set (maybe every 20-25k miles). Hey, gotta pay to play when you're pushing so much more power than stock.

I run these on my Speed3, I'm tuned at 21.5 PSI. These plugs have been great so far, about 4-5 months on this tune. Depending on your setup, you will probably have to regap. I gaped mine at .026. I will update this if I run into any problems.

These spark plugs are one of if not the cheapest and largest bang for your buck upgrade you can do to your car. I love them
