i'm up early with nothin to do so i checked mine. my 026, 044 and 660 all have bosch. my shindaiwa 377 has a champion. these are the plugs that were in the saws when i bought them.
 
Both good, a comment about champion, I have a 394xp I bought new the first year they came out with the same champion plug it came with never a problem.
 
NGK in the Husqvarnas, Bosch in the Stihls.

I tried a Bosch in a Husqvarna once and it would not even start. Tried the same plug in a Stihl and it fired up in two pulls. Put an NGK in the Husqvarna, and it started in two pulls. Both plugs were new and gapped to .020". Anyone know an explanation for this???

The Bosch plugs have good taste?
 
I've had the tips break off on Bosch plugs. I run NGK if I can. Champions are sometimes hit or miss, but I can't think of a specific time I've had a problem with them. Usually it's some other issue that fouls them enough, to put in a new one.
