Hi everyone.

Just wondering if I could get your suggestions. I currently own a 2005 C230k sedan (M271)

According to the maintence manual, its telling me that i need to change my spark plugs at 78k miles.. right now im at 76.5k. HOwever, I was getting price quotes from a few STEALERships on sparkplug replacement and all 3 mbz dealers are telling me that i dont need to change them til 100k.

Any suggestions? Should i change em at 78k or just wait til 100k. If i dont change them til 100k, whats the worst that can happen?

I've got Denso's in mine. Felt the difference immediately.

how much did you pay for the change and when did you do it (mileage?)

I bought the spark plugs (I think around $30 total at Auto Zone or Pep Boys) and one of my friends helped me change them. Not that difficult. The only one that is a little challenging is the closest plug to the fuel line (closest to the front). Took 10-15 minutes.

Drex and I have the same plugs - Denso Iridium IX IK20s - I've sinced changed my plugs twice (every 15K miles from when I first changed out the stock plugs). ~$40. Installation is cake if you've got the tools.

You'll most likely find them at Autozone.

Denso is proud of those plugs. Last month, they were $12.95+ each from AZ.
And I needed 12 of 'em! It does run a little crisper though.
