Just a simple FYI. The Platnuims I mentioned were in my 4.0 Xj for over 50K, never had a problem, only replaced becuase of milage, not performance. I have had bad run ins with the Champion plug. Thier great for lawn mowers and such. I have been told on more than one occasion that the platnuim plugs are pre-gapped, if you were to try and gap them, you'll mess up the electrode. Yes, always check the gap on any other type of plug but the platnuim type, wether its bosch or autolite.
