A Better Plug?

[rposton1]

I'm running MR43T AC plugs, I was wondering if there was a plug that was the same length, but had a extended electrode to keep it from fouling so easily. thanks in advance Rob

First you need to find out why you are fouling plugs.
Have you tried the Ac Delco Rapid Fire 10 plugs? They are supposed to be a better plug and they are also strainless like the MR plugs for the marine environment. Check them out, I have run several sets of them and I like them. I also like Nippondenso plugs.

AC Delco is the main problem, heat range may be wrong for the application also??????, Autolite or NGK's(right heat range) will correct the problem!..

AC MR43T = NGK BR6FS
Both are non power tip plugs.
NGK power tip is UR6
