I use these plugs in my two stroke scooter. I had been using regular plugs but I had to change them two to three times a season. In 2018 I switched to these Iridium plugs and I have only used 3 plugs in that time. So, while they may cost more than a regular plug but with buying two to three regular plugs a year the iridium plugs are a far better value than regular. I have never used them in a car but for a two stroke scooter these are the best plug you can use.

It's a nice spark plug, fit my motorized engine well, and lasts a long time.

Bought some of these for a Ryobi generator and they fit and run great. I’m hoping these will last forever since they’re iridium. Runs super smooth.

I have been using NGK iridium plugs in my vehicles and generators and performance has improved immensely from oem plugs. They provide a more complete burn.

It's a spark plug-- does what it's supposed to do and makes an engine run.I purchased this for a small 100cc inverter generator that takes this kind of plug-- they are kind of hard to find, I would have preferred a standard copper plug but this was able to arrive in the time I needed it.I should note the heat range (7) is rather cold, my engine was speced with a 6, but I haven't had any issues and don't expect to have any by going 1 heat range colder.

This works great and I feel like it gave my little 50cc moped a little bit of extra get up and go. I would buy another when the time comes.

I've been using iridium plugs for a long time in various vehicles. The main reason is the very long life of the electrodes. GMC caught on to the idea when they put iridium plugs in the pickup trucks and specified 100,000 mile life span for the plugs. NGK plugs are some of the best. In my motorcycles I find they are pretty much a set the gap, install, and forget 'em till you decided to have a look in a year of two.. I've covered some with soot from a too rick fuel setting and they still didn't foul out. I believe the tiny iridium electrode may ignite the mixture a bit better tan standard plugs simply because the mixture entering the cylinder will be able to surround the plug tip more completely. Well, that's my thoughts anyway. Seems like the engines run/start a little better. They won't show up on your fuel mileage checks or boost your horse power by some silly percent as the ads allude to, but they seem to be very dependable with the long life being the real advantage. Good product.

got these quickly for a good price, put them in my Ural a year ago and have not touched them since. Starts, runs, does everything a spark plug should do.
