Platinum spark plugs were developed in order to increase the time between plug changes (look at how many cars are advertised as going 100k between tune-ups). In fact, platinum is a poorer electrical conducter than copper but it lasts longer, that is less material is eroded over a given period of time. The recommended plug for the 4.0 Liter V8 is a bosch or, preferably, NGK multi electrode plug (I'd have to check the number). The dealer I use and the indy shop I use both tell owners to stay away from platinum plugs on these engines. A better spark is obtained from copper and that is what the engine management electronics are calibrated for. I also spent ~$6.00 each on the +4's before I learned this. The car runs much better now.

FWIW,

Jeff Hagner
