Which Spark Plug

Thanks everyone for the reply on where to get the COPs for expy. Now I have a questiion on the spark plugs. I see on RockAuto that they have either
Motor Craft Platnums with a nickel on the outside, or the Autolight Double Platnum. I want to stay with the MotorCraft or Autolight since people have much better luck over all. Thanks for the help.

Matt

I would reccommend the autolite xp iridium...the fine wire technology uses less voltage to create a larger flame kernal which in turn makes your coils last longer...still has a platinum pad on the gound electrode which allows it to be used as an upgrade to your double platinum plug
