Spark plugs

[mulrik]

Does anybody know what the right spark plug connector type for an early 250 is. I know it is the 1000 ohm, but was it the brown/red bakelite or a metal one. And please does anyone have six of whatever the original is for sale if I'm not lucky with Mercedes, Bosch or Beru???
Best,
Ulrik

Found this (below) on another Mercdes site:

Basicly says that the Bosch bakelite should still be available at part# MB # 000 156 26 10 and that the corresponding Bosch number should be # 0 356 100 022. Furthermore, Original metal Beru's are available, I guess you can work out the numbers...

Für den 280S W108 stehen bei mir die Stecker mit der # 0 356 100 022.
Das entspricht der MB # 000 156 26 10. Sie kosten ca. 4,50 Euro.
Das sind die braunen Bakalitstecker aus den /8.

Es gibt von Beru aber noch die alten Metallstecker. Die haben die Beru # 0300062101 und kosten ca. 10,00 Euro. Das entspricht der MB # 000 156 34 10, 000 156 49 10 und 000 156 52 10. Sie haben 1KOhm.

Den gleich Metallstecker gibt es auch noch von Bosch. Dort hat er die Nummer 0 356 301 022 und kostet ca. 9,50 Euro. Der Stecker ist ca. 105 mm lang und hat bei MB die # 000 156 28 10, 000 156 30 10, 000 156 34 10, 000 156 40 10, 000 156 49 10 und 000 156 52 10.

Beru metal are available at

I ran accross an add from NKG advertising their new Iridium spark plugs. These spark plugs as NKG claims offer superior ignitablitly with out sacrificing durability. the tapered ground electrode increases flame kernel expansion, while the superior heat range design is ideally suited to the demands of high performance enviroments. Specially designed to meet the needs pf serious enthusiast.
Iridium 1X spark plugs offer outstanding acceleration , high fuel efficency and long life.
The standard plug we use BP7ES is in the Iridium line a BPR7E1X stock number 4055 availible at NAPA stores. NKG technical can be reached at 877-4736767

Has anyone tried these out?

It's funny how these threads morph around...Bob Geco asks about Iridium plugs and suddenly there's a rehash of the plug wire connectors and resistance...

Anyway, Bob, I saw a "demo" setup of these at a foreign auto parts store where they showed you the plug in action and you could see how the flame/spark behaves as they say...I can't tell you whether this is worth a darn--certainly on our cars--but it was obvious.  Now, that being said, the plugs cost about $12.95 each or something like that--about 4x the cost of normal plugs.  I'd have to have some money burning a hole in my pocket first...
