Mercedes-Benz Iridium Spark Plug A0041598103 Z6S113320R Ignition System Upgrade

Mercedes-Benz Iridium spark plug A0041598103 (also compatible Z6S113320R) ideal for ignition system upgrades; fits post-2000 C-Class, E-Class, S-Class, and other MB models. Iridium electrode provides stable ignition and improved combustion efficiency; longer life than standard plugs. If cold-start hard, power loss, or high fuel consumption, replacement resolves acceleration hesitation and idle jitter.
