    Spark plugs

    Just wondering which spark plugs you all prefer? Have you had better luck with hot or cold plugs? I am going to run MSD plug wires and just wondering what you would recommend?

    If you have forced induction, most say to go 1 or 2 steps colder. The plugs will hit the ideal temp sooner. Otherwise. Id run stock.
    Drag racing...just another numbers game.

    Don't know a lot about this area...how do you know if the plug is a hotter or colder plug? I have the stock induction with the slp lid. Is there a part number that I can just take to a parts store and tell them those are the plugs I want?

    Spending $150+ for Granatelli wires is going a bit overboard IMO(especially for a stock engine). The MSD wires are around $55.00 and are fine.
