Main Benefits
- Better combustion efficiency
- Faster throttle response
- More stable spark at high RPM

Heat Range Information
The 9 in AB9R31 indicates a relatively colder heat range spark plug, which is more suitable for:
- tuned engines,
- high-compression setups,

- racing/high-RPM use.
Best Applications
This plug works especially well with:
- upgraded ignition coil (UMA FI coil),
- high-compression piston kits,
- ECU tuning,

- performance exhaust systems.
Important Note
For completely stock commuter motorcycles, a colder racing plug may sometimes:
- carbon foul during slow city riding,
- require proper AFR tuning,
- perform best under spirited/high-temperature usage.
