Well, I think I overpaid. I really see no difference from the stock plugs that were in there for 60k miles. I used ndk on my bikes for years and liked what I read about iridium holding up, so I thought I would give them a try. I think I could have went with champion and had the same results though. I plan on pulling the plugs to see how they have held up and as a pre-emptive maintenance.
