Hey guys,

Looking at my service booklet its saying to change the spark plugs approx 40,000kms or so on the C230K engines....why so soon? Its been done and stamped from MB as done from the previous owner at that mileage. I havent done them since I got the car and now it has 100,000kms but its running great!

Why would I need to change them and should i?
