All About Spark Plugs for 1992 Mercedes-Benz 400 SE

The spark plugs in your 400 SE provide the electrical charge that the car's engine uses to ignite its air and gas mixture; in short, they make combustion, and the car running on its own power, possible. You'll know defective ones, then, from misfires, engine failure, rough idling, the plugs' leads seeming wider than usual or corroded, and the plugs not conducting electricity as well (or at all). In any case, you'll have to replace them; how much that costs can depend on whether they're the kind that last 18,000 miles or 100,000, and on whether they're basic copper or higher-performance platinum or iridium. According to recent RepairPal data, expect to pay anywhere from $115 or so to $135 or more on average, if you have the job done at a Mercedes-Benz service center. You can save money going DIY, too; just follow any spark plug replacement directions your owner's manual contains, and make sure to work with a cool engine. Most of the time, you'll need socket wrenches, a wire gauge spark plug gap tool, a socket swivel, an extension bar, some anti-seize thread and dielectric silicone compound, safety goggles, and work gloves.
