Spark Plug Replacement

I installed 16 platinum plugs in my dodge durango and it has the same power and mileage as it did with the resistor plugs, but I don't have to change them every 30,000 miles, The platinums should last 100,000 miles

There's a revoluntionary plug on the market. Advance auto Parts sells them. You you don't like them you can get your money back. The company that makes them is PULSTAR. The website is http://www.pulstar.com/ I know three people who have tried them and they notice a difference. If you don't try them do like Pat has stated. Use a double plat plug.
