After reading the documentation on the plugs I decided to try them out and noticed less fouling and less consumption. You really have to read the documentation behind these plugs to fully understand how they work. The spark doesn't jump to all four ground electrodes at once, but whichever electrode has the least resistance which means the plug runs cooler. It uses an increased platinum tip along with Nickel-Yttrium electrodes for longevity. I was skeptical about these plugs at first but I feel they are indeed the most advanced plugs out right now. Give them a try.
