[W126 Coupe] Opinion on ignition parts & dust cover

[Mister McGoo]

Tom;

Myself, I'd try W9DC's.

I went through this "hotter plug" issue two years ago.  The engine is a 380 
Euro with 250,000Km.  Then I went back to the recommended original (W7DC).  
The theory is fine in a controlled environment, but unless you can control 
everything including the quality of the gasoline you pump, the results can 
be inconclusive.

In Europe they have designed the N. American engines and systems for our 
inconsistant quality, low octane fuel.

For those who are really enthusiastic, it may be fun to experiment with 
plugs; you'll do no damage as long as the physical dimensions are right, and 
if you actually believe you are gaining, that's terrific.

For most people it doesn't apply.
