Browsing the web and came across this. http://www.oppracing.com/products/265-brisk-sparkplugs/ 1.5 hp for a 600, 2 hp for a 750, 3 hp for a 1000, and up to 5 hp on a ZX-14? Personally, I am not sure how a spark plug alone can give you more hp. I know there have been statements made like this for cars, specifically the E3 plugs. Has anyone ever used these before, or heard these sort of claims? FTR, I am not loking to replace mine, as I just installed new NGK Iridiums not too long ago. Not wanting to turn this into a "what plug is the best" thread either. Just found it interesting that they claim increased hp.
