I actually went for it. First time I thought a gimmic type plug could actually be beneficial. I have an 02 wrx and I was in need of an oil change and the coolant in that was put in my car before I bought it was not phosphate free and it was rich. so I just changed everything and my car ran significantly better. I used the diamond fire plugs but I don't know how much that contributed considering I also put the right fluid in with the right mixture and royal purple oil after a well needed change when it was using penzoil. I think the plug makes sense in not only lasting long but providing a good chance for more even combustion?
