Snake oil.

The only thing that has proven to work effectively on igntion upgrades is either 1)upgrading to a better coil that puts out more energy or 2)an ignition with multi-spark technology that extends the spark duration.

Besides, if you are thinking about using them in the NSR, I would highly advise against. Splitfire doesnt make a plug with a slightly recessed electrode like ours, and I would hate to see an NSR engine ruined because the plug ground tab broke off from vibration.
