Spark Plugs??

I was just curious on what brand of plugs most of you guys prefer. Do you have a specific brand that you purchase for everything, or do you go by the specifications in the manual?
I was just wondering. Since I have been told some different things by my dealer on what plug to use.

My Shindaiwa/Redmax dealer recommends Honda plugs for 2 cycle engines, so that's what I use and I've had great luck with them.

On small engines and 2 cycles we prefer Nippon Densos. Second choice would be NGKs. Champions and other american plugs just don't last or work as well. On our larger gas engines that are american made Champions work better than NDs or NGKs.

I run NGK's also. They seem to last much longer in all my equipment.

My mustang street motor was a testing bed for many things. I tried many different types of plugs. Bosch sucks by the way. The NGK's lasted longer under harder conditions and were the most responsive. Autolites would come in second. My 600 hp race motor will run only NGK's.

Did you say 300 hours on an oil change? Thats a little extreme wouldn't you say? The manufacturer recomends 50 even with synthetics. I run synthetics and have never gotten the mfg to admit they are better.
