Thanks for this. I just got my plugs from Amazon and they seem to check out regarding the items listed in the article: insulator text looks authentic, caulking is very smooth, has a lot number (though I couldn't see the font difference between real and fake in the article), slight marks on the...

Thanks, decided not to use the CR5HSB. I bought the NGK iridiums on amazon. They are sold and shipped by amazon and lots of good reviews, so seems legit? https://www.amazon.com/dp/B000HDIP9I

Thanks for the heads-up. The iridium ones I bought seem to get good reviews, but if anything seems off I'll try swapping the plugs.

Sounds like iridium is the way to go for an extra $5. I don't expect to put a lot of hours on this generator, but better starting could be important. Couldn't get the old nut off easily so I'll just buy some spares. I think I'm gonna order NGK CR7HIX's since they seem to be more available than...

I tried to remove the tip on the Torch with smooth pliers, but no go. I think I'll just leave it on there and buy some nuts. The heat number for the Torch plug that came in the Pulsar is 7 which maps to NGK# 7. I have some NGK CR5HSB's already, but I think I'll get the NGK iridiums with the...

Thanks! Didn't know about that tool. Heat range is 7 for Torch and NGK, looks like it's 22 for Denso. If the heat range doesn't matter I could just use my CR5HSB's, but that seems risky. I guess the different specs on the iridium electrodes don't matter? They're slightly different from CR7HSA...

I actually have two of those I bought for a Predator 2000W that I ended up swapping out for the Pulsar (was a better deal and included dual fuel), but the heat rating is different, so I can't use them on the Pulsar.

Yes, CR7HSA is the recommended replacement for Torch A7RTC in the NGK chart, but the terminal is threaded. I need the solid terminal or the screw-on nut if that's acceptable--seems like the consensus is that it is.

Thanks for the reply. Is iridium preferable? Any reason to use Denso over NGK? Looks like I can get the NGKs from Advance Auto today. How hard do I have to torque the cap to get it off? It doesn't seem to be coming off easily--I don't want to damage the only confirmed good plug I have at the...

I bought a small Pulsar generator and it came with a Torch A7RTC spark plug. I keep seeing people say it's important to swap these for NGKs. The recommended NGK replacement seems to be CR7HSA, but it has the threaded terminal instead of the solid terminal the Torch has. Should I use a screw-on...
