Br9ecs?

on my tl1000s v twin sport bike, I gained just over 1 hp over fresh normal ngk's on the dyno, back to back, and the bike was cooled in between runs.

I def noticed a more crisp throttle response, and even with my richly tuned EFI, it has yet to foul either plug in over 12k.

stock plugs would last 6k-9k before getting loaded up enough to notice a little drop in performance.

granted, this is a 4 stroke bike, but the better plug tech is quite evident.

even the dyno operator had remarked that in all of his dyno experience, the iridiums do in fact give more hp over the normal type plugs.

many sportbikes even come with iridiums now, inc r6's and r1's.
