    NGK spark plugs

    Hi.

    Why did NGK changed the spark plugs ref number from BKR6EK to BKR5EK?

    I found this,

    but I can't understand what changed to put a hotter spark plug.


    Tks.

    BKR6EK and BKR5EK are 2 different products, they haven't changed the REF number for either.

    No. They only changed the recommended spark plugs for Astra G from BKR6EK to BKR5EK.

    They claimed "due to changes in fuels". But what changes?

    Tks.

    This may cool down the combustion's temperature?

    higher octane fuels, leads to a hotter burn. i'd stick to 6ek's.
