Why Spark Plug Condition Matters for Mercedes

Spark plugs are critical in Mercedes engines, where precise combustion and ignition timing help deliver smooth acceleration, refined power delivery, and strong fuel efficiency. Over time, plug wear, deposits, or fouling can lead to misfires, rough idle, and reduced performance.
