I am using the plug now. They are exactly the same length as the stock plug. They have two electrodes and cost about twice as much. If there is a horsepower increase, I cannot tell.
NGK Cr9ek
Anybody here use these plugs? i hear you get a little performance increase b/c these plugs go just a tad bit deeper into the well.
but i also heard that it can damage your bike?

I was concerned about the plug being longer, too. The truth is it is not. I look at the CR9E and the CR9EK side by side, every which way and they are the same length. The only down side as I see it is they cost about twice as much. I am curious how they will last. The make a similar plug that is used in the ZX-12R or Huyabusa that has a iridium electode but they cost something like $25 per plug, ouch!
I usually change plugs every 10,000 miles or so which comes out to more than once a year

I was never able to find a socket that would go down the well so I finally bought the Kawasaki tool. I don't remember exactly but I think it was about $10. Subsequently, (hellofa word) someone said that a Motion Pro socket would work.
