  • Spark plug question

    I have an 02 Road Star Silverado. Vance and Hines exhaust, and a rejeted carburetor. Finally went to a k and n air filter in the stock air box and noticed an improvement in the throttle response. I was wondering if putting in a platinum or iridium spark plug is worth it? OEM plug is copper.

    Thanks,
    Matt

    Absolutely not. Stick with the stock NGK5129 gapped at .035. That is the best for your bike.

      The platinum or iridium plug will last longer than OEM copper. I use iridium and don't plan on ever changing them. IMO it's worth it to not have to pull the tank every couple years to change the plugs. As far as performance you won't see a difference.

        See I thought the iridium wore out faster cause of the smaller in diameter electrode but I was more concerned with performance more than anything. Thank you for your insight

      I am running Ngk DPR7EIX-9 in mine with super good luck.

        I use the iridium because they last longer,but if you use the stock plugs you will be fine
        I'm so far behind I think I'm first
