    Hi
    Not sure if this has been asked before.

    But do I really need to fit these 25+ each spark plugs to my 2013 CBF MK2 bike when the MK1 has normal plugs.

    Thanks everyone

    It's been asked many times and I've read of folk fitting the SC58 recommended NGK CR8EH-9 (5666) nickel/nickle and CR8EIX0-9 (4218) iridium/nickle spark plugs to the SC64 and experiencing misfiring issues. I don't understand why that should be but there it is, NGK no doubt have their reasons for recommending their cheaper nickel/nickle and iridium/nickle spark plugs for the SC58 and the more expensive IMR8C-9H (3653) iridium/platinum spark plugs for the SC64.

    Note - Where Honda recommend changing the spark plugs every 16,000 miles NGK give their IMR8C-9H (3653) spark plugs a 100,000 mile service life, therefore I'd leave them until you get around to the valve clearance check and, assuming the engine is running as it should I'd not bother with that until 48,000 miles or more.

    Your money, your choice but if you must The Green Spark Plug Company are normally best value for spark plugs.
