My WD has J8C Champions in it, and they foul constantly. The WD does use some oil. Can anyone give me an Autolite or other number that would be a little hotter than the J8Cs? Has anyone else had numereous bad experiences with Champions like I have had? Years ago they were good plugs, now it seems like they don't last, and some are bad right out of the box. Thanks in advance for any help.

I figure the Champion haters would be out in force. I use them all of the rime without problem. I just got a set of N-3C's for the LP fueled G262 power unit on my C-II Gleaner. If you tractor is burning some oil try a J-12. You may have to use the extended tip version which might help you fouling problem. J-12YC.

The plug of choice is currently the Autolite brand. The hottest operating plug for your WD would be the 308.

Thanks, guys. Please understand, I don't hate any brand, but I haven't had any luck with Champions lately. For 25 years, that was all I used, but when I started having problems, I tried other brands, and they worked better. The first problem I ever had with them was in 2-cyl Deeres. That's when I tried Autolites. I don't think that the corporations care about the quality of their brand names as much anymore. I think that they believe that advertising and brand loyalty will carry them through.

If you try a bunch of differant plugs and they ALL tend to foul i would suspect a bad coil. Thats what i found.

If oil is fouling your plugs, another option is to buy some "spark plug extenders".....just a small fitting that goes between the head and spark plug.........one cylinder on my WD pumps a bit of oil........using an extender solves the problem.....as a matter of routine I clean the plugs once per year with a sandblaster....FWIW........RP

The Autolite 295 Is the same as the Champion J8C. I would try the Autolite 303 to start. You may also try anti-foul ends for the plugs.
