Hey guys, Ken here. Here's my experience with Platinum Plugs. I installed Autolite double platinums in my 94L about 6 months before I installed my Kenne-Bell supercharger. Everything worked out ok, until I started developing 8 lbs. of boost. All of a sudden the truck was topping out at 5000 rpm, then it would act like the rev limiter was kicking in from the the Crane electronics. After doing a hard rundown trouble shooting the fuel, and electronics, I remembered an old post on the nloc that talked about platinum plugs, and blowers. I pulled out the plugs, and found every plug to have the outside electrode burned clean off. The only explanation I can give for the fact that it ran smoothly at idle, and up to 5ooo rpm is the the hi voltage electronics. Bottom line is "dont forget the plugs". BTW, I since have gone to the standard autolite coppers, and am well pleased with the results. KEN |
