Spark plugs are the pieces of equipment that provide the spark to engine cylinders, thereby igniting the mixture of fuel and oxygen that powers your Mercedes 450SL's internal combustion engine. Spark plugs wear out overtime, causing performance issues that can vary from rough idling to cylinder misfires. Automobile manufacturers recommend replacing spark plugs at least every 30,000 miles. Most drivers, however, replace their spark plugs and sparkplug wires every time they tune their vehicles. You can buy replacement spark plugs for your Mercedes 450SL at PartsGeek.com.

Spark plugs receive high voltage current from the ignition coil. At the sparking end of the plug, there's a tiny gap between two tiny pieces of metal. The spark generated by the plug must jump this gap. Over time, the gap gets wider and the spark generated by the plug becomes unable to bridge the required distance.


They are available for the following Mercedes 450SL years: 1980, 1979, 1978, 1977, 1976, 1975, 1974, 1973, 80, 79, 78, 77, 76, 75, 74, 73. This part is also sometimes called Mercedes 450SL Spark Plug. We stock spark plugs parts for most Mercedes models including E320, C230, ML320, S500, C280, C240, 300E, S430, ML350, 190E, SLK230, CLK320, ML430, C320, SL500, CLK430, E350, 560SL, E55 AMG, E500, 380SL, S600, 420SEL, S320, C300, E430, S420, 500SL, 560SEL, 300SE, R350, ML500, E420, C220, 300TE, CLK55 AMG, 500SEL, 260E, 300CE and SLK320.
