Yep, I installed a set last spring but ended up pulling them right back out and reinstalling the OEM plugs. BTW- for those that haven't tried it, removing and replacing plugs is a real pain on these bikes. Access in general is not great and because they are recessed, you run the risk of cross-threading them unless you are fairly inclined mechanically.
I was initially taken in by the advertised claim of increased HP with Brisk plugs. However, for reasons unknown, they immediately fouled-out with thick carbon deposits around the electrode band. The problem disappeared when I reinstalled the OEM plugs. I returned them to the supplier (OPP) who was less than helpful (they simply returned the foulded plugs back to me).
There may be '08 owners out there that swear by these Brisk plugs, but imho you can't beat the stock NGK plugs.
