Mercedes-Benz Spark Plugs FAQ

How Can I Tell if the Spark Plugs in My Mercedes-Benz are Bad?

From the engine misfiring or failing, from the plugs' leads seeming to have widened or corroded, and from the plugs not conducting electricity quite as well (or at all).

How Much Does Mercedes-Benz Spark Plug Replacement Cost on Average?

Anywhere from $215 to $280, per RepairPal. That's whether they're the kind that last 18,000 miles or 100,000, and whether they're the basic copper kind or higher-performance platinum or iridium. Getting them replaced at a Mercedes-Benz dealer can add another $130 to $170. Cost can also vary by model; Mercedes-Benz E 350 spark plug replacement, for instance, can run between $325 and $370.

Can I Change a Spark Plug Myself?

Yes. It's simple; you can find your model's specifics in your owner's documentation. Start with a cool engine, and grab the tools you'll need (among them, socket wrenches, a wire gauge spark plug gap tool, a socket swivel, an extension bar, and anti-seize thread and dielectric silicone compound), plus some safety goggles and work gloves.
