In Reply to: iridium plugs for Bmw, check the dynotests and the posted by Bill R. on August 01, 2001 at 13:09:49:

like those Dyno tests are within the margin of errors for these kinds of things, its also kind of strange to see MPH on the bottom scale and not engine RPMs. but in any event, unless the base engines are reengineered to take advantage of these kinds of things, or if other ignition components are added/modified, i really can't believe you would see any difference whatsoever.

the power of the spark is due only to the amount of power used to jump the gap. unless there is some theoretical gain in consistency in the spark over copper plugs, which admittedly they claim, i just can't see that you'd see much of a benefit

now i'm speaking mainly about the relatively low-tech M30, i don't have any great knowledge about the V-8s or the M50TUs


price....
