Some time this spring I'd like to pop some new spark plugs in my\nwife's '98 3.0 V6 Voyager (Vger). This one has the Mitsubishi engine.\n\nWhen I got the car two years back, it had 66K miles on it and when I\nreplaced the plugs, they looked like the originals, they were that\nbad. (Never have I seen such bady worn plugs!) I replaced those plugs\nwith Bosch Platinum plugs (regular plats, not the 2s or the 4s) The\nVger now has about 75K on the clock.\n\nFrom personal experience in other cars and also from reading on the\n'net, the original Bosch Platinums may not be the best plugs when one\nis looking for a long-lasting plug.\n\nWhat do people recommend? The Bosch Platinum+4s? Bosch Platinum 2s?\nAutolite Platinums? Denso Iridiums?\n\nI don't mind spending more if the plugs are long-lasting premium\nplugs. The Vger is only driven about 4K a year around town, so these\nvery well may be the last plugs I put in the car.
