    we've had our Z3 for just under 2 years now, it's always had a slightly lumpy tickover which I think is quite common for the M44. I changed the spark plugs 18 months or so ago with Bosch Super4's and never really noticed any change with the tickover.
    Last week I ordered a set of NGK Iridium IX plugs and fitted them a couple of days ago, wow what a difference, the tickover is much improved and the engine feels far more responsive through the gears, at least another 30bhp o_O probably!
    When it's time to do your next service I would seriously recommend trying a set, these are the ones: BKR6EIX 6418

    :thankyou:

    +1 on these, they are the upgrade plug option, had them in my car for three years now

    I've noticed too the big difference between the Bosch and the NGK recommended in the owner's manual!
    So next Inspection I'll try also the up graded Iridium!:)
    Thanks for sharing!;)

    Sounds good - a quick Amazon search shows them @ ~£41 for four - is that reasonable?

    Too expensive £20 maximum but should get cheaper than that
