    I bought mine on Ebay. NIB and very reasonable. They have been great, and I think they will go the distance. Hope it helps.

    Be careful trying to gap iridiums. The iridium will flake and could cause issues. I put them in my 115 and run them like they came. I know it's not a SHO but just sayin.

    I set my Iridium set at .040 So far has been spot on.
