Description
FEATURES
- Unique electrode shape maximizes the power created by the spark plug - Diamond Fire technology
- Electrode is a combination of performance and technology that results in an improved flame kernel shape
- This flame front ignites the bulk air/fuel mixture faster, moves heat into the combustion chamber faster and creates a more localized pressure front for faster pressure rise during the cylinder power stroke
- The result is more complete combustion and an improvement in engine performance
- A truly premium performance plug

Vehicle Information
Indian Roadmaster Motorcycle - Street (2015-2026)
The Indian Roadmaster, produced from 2015 to 2026, is a premium touring motorcycle renowned for its comfort and performance. It has evolved over the years, offering a refined long-distance riding experience. Initially equipped with the Thunderstroke 111 engine, it has seen significant improvements in its powertrain and technological features.
The 2015-2026 period saw significant changes. The Thunderstroke 111 engine (1811 cc) was replaced by the Thunderstroke 116 (1890 cc) around 2020, increasing torque. The most notable shift occurred in 2026 with the introduction of the liquid-cooled PowerPlus 108 (1768 cc) and 112 (1834 cc) engines, marking a departure from the air-cooled Thunderstroke. Trims like the Dark Horse, Limited, and Elite also expanded the lineup, alongside the standard and Classic Roadmaster. Continuous technological updates, including the Ride Command system and comfort features, were integrated throughout this period.
