  • For Those Who Run Irridium Plugs . . .

    Looking to finally installing them tomorrow. I read that brass inserts are used in-place of the resistors in the caps. Is the brass something I can find @ Home Depot, or hobby shop only? I think we have a Ryder's here.

    I just put thick copper wire in the ht caps. I've also wrapped silver foil around the original resistor and put it back in. Both methods work fine..

      Anything wrong with just using the NGK 6637 as is ?

        HT caps have a built in, removeable resistor but iridium plugs have a resistor already inside them. I removed the resistors from the HT caps and replaced with copper wire in order to get a bit more oomph to the plugs...it seemed pointless having two resistors in series before the power gets to the plug..

            Btw, as posted in another thread, I replaced the resistors with solid core copper wire from Home Depot. Not sure I notice any difference between the two plugs.
