How to confirm the right plug for your Shine
To ensure you install the correct spark plug, follow these steps:
- Check the owner’s manual or Honda service bulletin for your year and market to confirm the recommended part number.

Using the wrong plug can affect starting, idle quality, and fuel efficiency. If you need a quick cross-reference, provide your bike year, market, and the current plug's markings to a parts specialist.
