car is running fine
2004 clk 500 with 23,000 miles on it. should i change the plugs?
on 2004 Mercedes-Benz CLK500
This engine calls for the equivalent of a Champion KC11PYP spark plug which are fine for 60k miles in my opinion, many would say leave them in for longer but if it were mine I would change at 60k.
Thanks for the info saved me about 400 bucks
