Bosch NOS spark plug F7DC0 – Made in Germany – original Bosch quality – Mercedes M104, M111, M119 and M120
This original Bosch NOS (New Old Stock) spark plug is an unused original Bosch spark plug from old factory stock, produced in Germany according to the original Bosch specifications and quality standards. The Bosch F7DC0 was prescribed by Mercedes for various M104, M111, M119, and M120 engines and is known for its excellent quality, reliable ignition, and long service life.
Original German-made Bosch spark plugs are considered by many Mercedes specialists and enthusiasts to be of the highest quality. Thanks to precise manufacturing, high-quality materials, and consistent quality, these spark plugs ensure optimal combustion, smooth engine operation, and excellent cold start characteristics. Original Bosch NOS spark plugs are becoming increasingly scarce and are therefore highly sought after for maintenance and original restorations.
This spark plug is suitable for a large number of Mercedes models with M104, M111, M119, and M120 petrol engines.

Important
Always check new spark plugs for transport damage before installation. Dented packaging may indicate that the ceramic insulation part has sustained a hairline crack. Damaged ceramic can come loose during use and cause serious engine damage.
Always check the prescribed electrode gap before installation. Even original Bosch NOS spark plugs may have a deviating electrode gap due to prolonged storage. If necessary, carefully adjust the gap according to Mercedes factory specifications.
We recommend replacing spark plugs preventively every 8 years or 30,000 kilometers to replace, depending on which is reached first. Even in vehicles that are driven infrequently, the electrodes and insulation material can deteriorate due to aging, which can lead to a weaker spark, rough engine operation, higher fuel consumption, and reduced cold starting.
For optimal performance, we recommend always replacing spark plugs as a complete engine set. Simultaneously check the condition of the spark plug wires, distributor cap, and distributor rotor to prevent voltage loss and ignition malfunctions.
Always check before purchase and installation whether the part is suitable and equivalent based on photos, description, and specifications; installed or used parts cannot be returned.
