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
Harley-Davidson Heritage Softail Motorcycle - Street (1986-2017)
The Harley-Davidson Heritage Softail, produced from 1986 to 2017, is a classic touring cruiser known for its nostalgic styling and hidden rear suspension. Over its production run, it evolved through several engine generations, starting with the Evolution engine (1986-1999). In 2000, it transitioned to the Twin Cam 88B, followed by the Twin Cam 96B in 2007, which also introduced a 6-speed transmission and standard electronic fuel injection. The final engine upgrade within this period was the Twin Cam 103B in 2012. Key trims included the long-running Heritage Softail Classic (FLSTC), the limited-edition Heritage Softail Nostalgia (FLSTN) from 1993, and the retro Heritage Springer (FLSTS) from 1997-2003. ABS became standard in 2017. This period saw significant mechanical updates while retaining its iconic aesthetic. FAQ:

A: Please use our year and model selector to ensure compatibility with your motorcycle's exact specifications. Q: Are parts interchangeable across all Heritage Softail years?
A: Due to significant engine and transmission changes, parts compatibility varies. Always use the year/model selector for accurate fitment.
Maintenance
| Component | Interval | Details |
| Engine Oil and Oil Filter | Initial: 1,600 km. Subsequent: Every 8,000 km. | A 'three-fluid service' (engine oil, primary, and transmission) is often performed every 8,000 km for convenience. |
| Drive Belt (Rear) | Inspection and adjustment: Initial 1,600 km, then every 8,000 km. Replacement: 80,000 km to 160,000 km. | |
| Spark Plugs | Variable | For Twin Cam engines, every 32,000 km. Other general recommendations are every 16,000 km or 2 years, or every 48,000 km. |
| Air Filter | Inspection: Initial 1,600 km, then every 8,000 km. | For Twin Cam models, inspection every 16,000 km may be recommended due to larger air filters. |
| Coolant | Not applicable | These models are air-cooled and do not use liquid coolant. |
Maintenance intervals can vary slightly by year and engine. It is recommended to consult your specific model's owner's manual for precise information.
