Has anyone tried these plugs? if so did you notice any difference over the stock plugs?? Can someone give me the NGK number for the plugs in our bikes.

I am at work, so I don't have the number. I put them on last winter. They work good. Did not notice that much of a difference though. Some people say "side gapping" the plugs is much better. Just mod your existing old plug. Data may be in tech vault.

Autozone will probly have our ngk dpr8ea9 on the shelf. make the counter guy look, I almost didn't get them because he says they only carry a few ngk. Same thing last year at a different Autozone. I'm not complaining about Autozone, I am actually happy that they carry something for us.

I got a set from Brent (newspeedmaster.com). I didn't notice a big difference, but the throttle response was better. The last time I did some long distance highway driving I averaged over 45MPG running at 75MPH.

Not very scientific, but I started her up and let her warm up and checked the tach and it read 1000. Shut her down and replaced the stock plugs with Brents NGK IX Iridium and started her up and the tach now reads 1150.
Just went out yesterday for the first time and really took it easy but a couple of spots I was able to get on it and she flew. Did the freak this winter and re-jeted with shims so I can not say the improvement in performance is due to the plugs.

I really didn't notice anything different. MY bike only had 3K on the original plugs, and I replaced with iridium. I would think the benifit is thay would last longer than the std ones.
