M.B. Doc:
I just changed all 6 of my spark plugs on my 300E, with Bosch H9DC. The previous plugs were the Bosch H9DCO that I put in last summer. The H9DC's say their made in Germany--not India. So whats the difference anyway between H9DC and H9DCO?? Will the H9DC plugs that I put in harm my engine in anyway??? I've heard that these H9DC were made in India, but mine had the words engraved on the plug "Made in Germany".
