Drag Specialties — Spark Plug (Manufacturer's reference: E18-6729IDS)
Designed for demanding riders and long touring stages, this Drag Specialties spark plug utilises iridium technology to provide reliable combustion and increased longevity. The iridium electrode, thinner than a standard electrode, requires a lower voltage while producing a hotter spark than conventional plugs — an advantage for a crisp and consistent ignition on large touring twin-cylinder engines.
Ideal for the Touring category, this spark plug is suitable for high-displacement motorcycles and is among the recommended choices for models such as the INDIAN CHALLENGER 108 ABS (Limited, Elite, Dark Horse) 2024 (1768 cm3). Do not promise anything unverified: it offers a hotter spark and better longevity compared to standard plugs, without any undocumented guarantees.
