Honda does not rely on a single spark plug brand. In practice, Honda's original equipment plugs come from either NGK or Denso, depending on the engine family and the market.
The brand for your Honda spark plugs is specified in official documents such as the vehicle's owner's manual, service bulletins, and the Honda parts catalog. While many models use NGK plugs, others use Denso plugs, and some markets may differ. If you're replacing plugs, always match the exact Honda part number or the recommended heat range, thread size, reach, and gap.
Brand options Honda uses for spark plugs
Two brands are commonly used as original equipment by Honda engines:
- NGK
- Denso
Conclusion: The two main OEM spark plug brands Honda uses are NGK and Denso. Which one applies to your vehicle is dictated by the engine family and market; always verify the exact part number in the owner's manual or Honda parts catalog.
Determining the right spark plug for your Honda
To get the right plug for your vehicle, follow these steps:
- Check your owner’s manual or service bulletin for the spark plug specification, including heat range and thread size.
- Look up the OEM part number in the Honda parts catalog or a dealer portal; the catalog will show whether NGK or Denso is specified for your engine.
- If using aftermarket plugs, select ones that meet the same heat range, thread size, and reach that Honda specifies.
- Verify the spark plug gap before installation; many modern Honda engines require a specific gap as listed by Honda.
- Be aware of market variations; some regions may list a different brand as the OEM based on supplier contracts or emissions requirements.
Conclusion: The spark plug brand Honda uses depends on the model and market; NGK and Denso are the two main OEM suppliers. Always verify the exact part number and specifications from the owner's manual or Honda parts catalog before buying.
Summary
Honda does not stick to a single spark plug brand across all models. The brand is chosen from among NGK and Denso based on the engine family and regional market. For any replacement, verify the exact Honda-recommended part number and specifications in the owner's manual or official parts catalog to ensure compatibility and performance.
