In the Spark Plugs subcategory, you’ll find suitable plugs for numerous Alfa Romeo models as well as other classic and modern vehicles. The spark plug generates the ignition spark in the combustion chamber and is crucial for starting behavior, idle stability, acceleration, and emissions.
We offer spark plugs with various heat ratings, thread lengths, and electrode designs – tailored to compression ratio, engine type, and ignition system. In addition to standard copper-core plugs, we also supply platinum and iridium versions for greater thermal resistance, longer service life, and improved ignition performance in electronic ignition systems.
All plugs are precisely matched to the engine’s requirements, ready to install, and ideal for classic ignition setups as well as modernized upgrades. For engines with multi-valve technology or high specific output, we also provide advanced solutions with optimized spark propagation and clean flame pattern.
