are they ok to run in a stock itr?

I know there has been plenty of posts but none concerning these plugs, Advise?

 

Com'on does anyone know about these?

 

I used to run these spark plugs in my R when it was stock and there was no problem. I don't see why there should be....
I still run the sparks at the recommended gap and still no problem. More else, I see some advantages

 

"More else, I see some advantages "

Such as; better throttle response, better gas mileage, and they're supposed to last longer than platinum.
