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 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.

I am using them too.....power increase is slight to none,but in the full package of jet kits and slip ons and shit like that they can't hurt.....probably at best, getting a more consistant burn pattern.....that is what the masses say is happening.

I'm thinking I am getting a helping hand at fuel milage..my bike runs a tad rich and this might be helping a little.....maybe.

how often do you guys change your plugs? i read that since they are about 1mm longer, carbon might build up on the exposed threads. and you should change them often.

I ride a 99 Zx6r by the way...how about you?

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 just went to go change the plugs on my bike to CR9EK's and i was almost there..when i got to the plugs , i went to go to my kawi tool and the damn thing is bent from the previous owner...

is there anything else i can use? i tried to use a socket with an extension, but there is just not enough room for it...plus i'm afraid the socket will get stuck down the well..

also, how the heck do you guys work in that tiny area? i followed the factory service manual, and there to work in, is so small

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.

I also have never found a 'spark plug wrench' that fits in all spark plug wells . As Esjohnsey says, there too darned fat. I have discovered that a standard socket from Sears, and presumably anywhere else, works just fine. I also use a special six-inch extension with a locking system so the socket cannot come off. These are available from any of the big tool companies (but not Craftsman, yet anyway). Once you have one, you really appreciate not having to fish the socket out of the plug well ever again.

Dave,
I tried using the extension, but there just doesn't seem to be enough room for me to fit it in b/c of the angle the well is. The frame of the bike gets in the way.

or am i just to much of a novice?
