This isn’t an automotive application. Far simpler design of a knockoff Honda engine.
As some may recall, my old Robin Subaru inverter generator started on fire, so I got an HF Predator 3500 inverter. I was at about 20 hours, so I decided to do a break in oil change and spark plug exchange. The change from the HF “Torch” plug to an NGK iridium is a recommended upgrade.
The generator is quiet, but not low pollution. I can smell it much more than my 1700W robin or 1000W Honda, even when just idling. It also didnt idle perfect. Not bad, not troublesome, just not perfect.
All of that has changed with the NGK, idle sounds and smells much changed. The old plug didn’t look bad, the new one is just much better.
What is the part number of the NGK plug you are using now? Was the old plug Torch F6TC?
Maybe generators are different but i ran some tests and compared an ngk plug vs an E3 and i consistently get more mowing time with the E3 plug.
If your application is a Predator 3500 inverter generator, the factory plug was F7RTC which cross references to NGK BPR7ES (copper) or BPR7EIX (Iridium.)What part # NGK plug did you use and what was the Torch #? I want to change mine too

I have both a Champion 3500 Watt open frame generator with 196 cc Chonda and an Ariens Deluxe snowblower with 254 cc LCT. Both of these were supplied with Torch F6RTC which cross reference to NGK BPR6ES (copper) or BPR6EIX (Iridium.) I suppose the enclosed nature of the Predator inverter generator calls for a cooler plug.
I've stated this elsewhere on these forums: two of three Torch plugs performed well for the limited time they were used (20-40 hours.) The one in the snowblower was trouble from the get go. It's an entirely different machine with the NGK Iridium plug. Note that if you go to Lowe's for a replacement plug for Ariens, what you will get is an Ariens branded Torch plug. I worked four moths in the OPE department at Lowe's this spring and got more than a few curious looks when recommending the Honda branded NGK plugs over the other OEM plugs (usually B&S branded Champions.) Never did anyone come back and tell me that that was a bad call.

I really like Bosch Platinum and have been using them for over 25 years.
