Just completed changing the spark plugs on my 2003 C230 Sport Coupe. The directions posted by MrCoyote and tips included were excellent. Thanks very much to his good work the job went very easy and took about 45 minutes.

My car works so much better, better performance and easy starts, and I will find out tomorrow but I am guessing improved mileage.

This forum rocks, thanks to everyone.

Cheers,

Thanks for the kind words. I'll bet next time you could do it in 30 min., right?
And you saved paying somebody to do a job that's relatively easy too.

Have you done your fuel filter yourself too? That's another one where you can save
a bundle if you buy the filter yourself online and do it yourself.
