It's just my opinion but I can't stand champion plugs. (sorry guys)
I've had the best luck with plain old Autolights. My plug always looks good and they last along time. (hey, their cheap too [img]/wwwthreads_images/icons/smile.gif[/img])
Always keep in mind that a good plug won't fix a carburation or ignition problem.
Even if they were almost the same (there not[img]/wwwthreads_images/icons/wink.gif[/img]) in my neck of the woods the platnum chumpians are 2 to 3 times as much. I'm a cheap ba$tard.
Bad apple? Who me?
If I was going to spend a few mure bucks on plugs I'd buy NGK(I think) hot U plugs.
Let the great sparkplug debate continue.
Champion has got there act together in the past few years, but I have really become an NGK fan. The only plug I sell that has not got any negative feedback. I use NGK in all of my vehicles. I sell Champion, Autolite, AC, and NGK. I sell more NGK's than all other plugs combined.
