this spark plug?

[timmyj51]

Gonna change the plugs on my C220. Instead of the
OEM Bosch F8DC4 am thinking of using the Bosch
Super Plus plug with the Yttrium electrode. Anyone know if this plug is
any better than the OEM one? Any worst?

i've used it the last 2 times on my c280. good all around plug. no power or fuel change but idle was perfect! great plug for the money.

from what i have read in the forums are engines respond good to the bosch plugs . better yet the copper ones . people who used those newer style plugs with platium, and other names i cant spell dont respond or act any better. just do a search on this and it will pretty much tell you what not to buy...

Once you stray away from Mercedes recommended OEM Bosch F8DC4 for the M104 engine C280 and C36 you enter unknown territory.

There is a lot of negative comment on the use of other than OEM non-resistor copper core plugs in many many forums over the years.

Do your own research and make your choice at your own peril...
