Description
Spark Plug Vittorazi – Factory R
This is compatible with the Factory R.
It is highly recommended to replace every 20 hours for peak performance.
Key indicators that it’s time to change your spark plug:
- You’re having a hard time starting your motor – this is the clearest sign.
- Your motor is still running rough after you’ve tuned it.
- Also check the tip of the spark plug; different color browns indicate how your motor is running – a caked brown is a clear sign it’s time to change out.
