    Best Ultra250 plugs?

    Hey guys, now that some time has passed, is there any new info on which plugs work best in the ultra? I did search this and found lots of older info, but wondered if thats changed, thanks!

    This has been discussed quite a lot and I personally do not feel that a consensus has been reached. I personally would recommended the PMR9B as that is the "only" plug recommended by Kawasaki for the Ultra 250X/260X. Some here say that the CR9EX is just as good (cheaper too).

    well as for a consensus being reached it has!

    they are cheaper , they last a full season easy when you ski is running correctly
    because they are not made from ant prescious metal it can handle contaminations better, oh there cheaper
    most platium and irriduim hate working out side the right enviorment( they fail easier)

    I have been using the NGK standard range plugs in every turbo/supercharged car, bike ,ski,mower for the last23yrs and they are fine.

    if some one wants to spend shit loads on a Suggested plug then fine their choice. Just dont complain they are to dear when they crap out

    CR9Ek is more than suited for the job

    end of it my shitty CR9EK are 40hrs old now and still look like new

    What about the NGK CR9EIX? It < $1 more per plug than the CR9EK and I have heard it reccomended more than the CR9EK as a PMR9B substitute. Maybe that would be the best compromise? I can only speculate as I have only used the PMR9Bs.

    yes the EIX is a better plug, yes I have used them and no trouble, but I get good hr's from my EK's so I am happy.

    also other skiies that I have built and service have had great sucess aswell.

    but it's up to the individual

    I bought the EIX's and they crapped out just like my PMR's did.....seemed to last a bit longer though.
    Been running the EK's ever since.
    Still have every plug thats been in the ski collecting dust.....along with all the catch can liquid in a big jug.....weird i know
