YAMAHA AEROX 155 UMA RACING UTECH IRIDIUM SPARK PLUG AB9R31 02AR0068 02SP0003
02SP0003 is the UMA Racing UTECH Iridium Spark Plug AB9R31 a high-performance iridium spark plug designed for higher combustion efficiency, stronger ignition, and improved throttle response.
Main Benefits
- Better combustion efficiency
- Faster throttle response
- More stable spark at high RPM
- Longer service life than standard copper plugs
- Improved ignition consistency
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,
- aggressive riding,
- racing/high-RPM use.
Best Applications
This plug works especially well with:
- upgraded ignition coil (UMA FI coil),
- high-compression piston kits,
- ECU tuning,
- big throttle body setups,
- 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.
