I think so. I quit using glow plugs from Fox, K&B, etc... after seeing them burn out too quick. I use only two plugs. I use OS #8's for most of my 2-stroke glow engines and OS "F"'s for 4 strokes and big glow engines. Every once in awhile I will will use the cheap OS A3 in small glow.
Maybe I am paying too much for glow plugs. But these last and I don't have to worry about them.

I agree with Cheech but would add the K&B HP plug. I use it on my Webra 32 with mousse can pipe and they hold up better than the OS#8 plug.
