Spark Plug Question
I am currently running Bosch copper "H9DC" plugs in my 300E. last time i changed them they replaced the "H9DCO" that i had in there. my question is.... what does the "O" stand for?? whats the difference?
Thanks, Adam

Bosch's German site has the information. Go to http://www.bosch.de/aa/en/produkte/zuendung/zuendkerzenkunde/ and click on "Bosch spark plug type designation key". It gives a very complicated chart. Some things are pretty clear, others are a little more obscure.

"O" is for a heavy duty center electrode, i recommend using the plug with the "O" on the end whenever it's available.
