    I'm sure this question has been asked and answered before, but which are the best plugs for the 660 turbo engine? Are there any brands of plugs to be avoided? I'm getting the intermittent misfire and hope a change of plugs might solve the problem!

    These are japanese iridium plugs, do not use Bosch, Champion, Brisk etc - they might not work.
    If you have a missfire, a defective coil pack might also be the culprit

    Thank you for the advice Salieri. Is there only one coil pack per engine for all 4 plugs, or is there one coil pack for each plug. In other words is the coil pack the big square thing above each plug or is it elsewhere?

    Its one coil per plug, if you have the missfire on the same cylinder every time, try changing the coils around and see if the missfire moves; if it does you know which coil is defective
    The coils for the 0.7 Turbo are hard to acquire, so I hope its not that :D
