Spark Plugs for WD

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.
