The average cost of a Mercedes spark plug is between $3.29 and $307.02.

Mercedes spark plugs are an essential part of the ignition system in any Mercedes vehicle. They are responsible for providing the spark needed to ignite the air/fuel mixture in the combustion chamber. The spark plugs are typically located in the cylinder head and consist of a threaded metal shell with a center electrode and a ground electrode. The spark plug is connected to the ignition system via a spark plug wire, which carries the high voltage spark to the spark plug.

The purpose of the spark plug is to ignite the air/fuel mixture in the combustion chamber. The spark plug is responsible for providing the spark that is needed to ignite the mixture inside the combustion chamber. The spark is created when the voltage from the ignition system is applied across the electrodes of the spark plug. This causes an electric arc to form between the electrodes, which in turn ignites the air/fuel mixture.

In addition to the spark plug, the ignition system in a Mercedes vehicle also contains other related parts. These include the ignition coil, distributor, spark plug wires, and the ignition control module. The ignition coil is responsible for transforming the low voltage from the battery into the high voltage needed to create the spark. The distributor is responsible for routing the high voltage to the correct spark plug. The spark plug wires carry the high voltage from the distributor to the spark plugs. Finally, the ignition control module is responsible for controlling the timing of the spark.

Signs of Faulty Mercedes Spark Plugs

Signs of faulty Mercedes spark plugs can include a misfiring engine, poor fuel economy, a decrease in acceleration, rough or unstable idle, engine stalling, or a check engine light. The spark plugs in a Mercedes are responsible for igniting the fuel-air mixture inside the engine, which then powers the vehicle. When the spark plugs become worn or corroded, they are unable to ignite the fuel-air mixture as efficiently, resulting in a decrease in engine performance.

  • A misfiring engine is one of the most common signs of faulty spark plugs. This occurs when the spark plugs are unable to ignite the fuel-air mixture in the engine, resulting in the engine missing out on a power stroke. This can cause a noticeable decrease in engine performance, as well as a rough or unstable idle.
  • Poor fuel economy is another symptom of faulty spark plugs. When the spark plugs are unable to ignite the fuel-air mixture efficiently, the engine is forced to burn more fuel to make up for the lack of power. This can result in a decrease in fuel economy, as the engine is using more fuel than necessary.
  • A decrease in acceleration is another sign of faulty spark plugs. When the spark plugs are unable to ignite the fuel-air mixture efficiently, the engine is unable to generate as much power. This can result in a decrease in acceleration, as the engine is unable to generate enough power to propel the vehicle forward.
  • Engine stalling is another symptom of faulty spark plugs. When the spark plugs are unable to ignite the fuel-air mixture efficiently, the engine is unable to maintain a consistent power output. This can result in the engine stalling or cutting out, as it is unable to generate enough power to keep the vehicle running.
  • Finally, a check engine light is another symptom of faulty spark plugs. When the spark plugs are unable to ignite the fuel-air mixture efficiently, the engine control unit (ECU) will detect the lack of power and trigger a check engine light. This is a warning sign that the spark plugs need to be replaced.

Types of Mercedes Spark Plugs

Mercedes vehicles are equipped with several different types of spark plugs, depending on the model and year.

The most common type of spark plug used in Mercedes vehicles is the conventional spark plug. This type of spark plug has a single electrode and is made from a copper core with a nickel-alloy outer shell. The conventional spark plug is designed to last up to 100,000 miles and is the most cost-effective option.

Another type of spark plug used in Mercedes vehicles is the iridium spark plug. This type of spark plug has a much smaller electrode than the conventional spark plug and is designed to last up to 150,000 miles. The iridium spark plug is more expensive than the conventional spark plug but offers greater durability and performance.

The final type of spark plug used in Mercedes vehicles is the double-platinum spark plug. This type of spark plug has two electrodes and is made from a platinum core with a nickel-alloy outer shell. The double-platinum spark plug is designed to last up to 200,000 miles and is the most expensive option.

No matter which type of spark plug you choose for your Mercedes vehicle, it is important to ensure that it is properly installed and maintained. This will help to ensure optimal performance and fuel efficiency.


Mercedes spark plugs typically last between 30,000 and 100,000 miles, depending on the type of spark plug and driving conditions. Spark plugs are the most important part of the ignition system and are responsible for igniting the air-fuel mixture in the combustion chamber. Over time, spark plugs wear out and need to be replaced. It is recommended to replace spark plugs every 30,000 miles as a preventative measure. If you drive in extreme conditions, such as in heavy traffic or in extreme temperatures, it may be necessary to replace the spark plugs more frequently.
