The spark plugs used in a Honda CR-V depend on the model year and engine type. In the current generation, Honda generally specifies iridium long-life plugs from NGK or Denso, with the exact part number tied to the engine code and market. To be certain, consult the owner’s manual or a Honda service bulletin for your VIN.
Understanding which plug fits your CR-V
To ensure you install the correct spark plugs, identify the exact engine and model-year configuration of your CR-V. The steps below outline how to locate the right plug and why the choice matters for performance and reliability.
Engine families and plug types
Current generation CR-V (2017–present) with 1.5L turbo
These models typically use iridium long-life plugs and are commonly serviced with NGK or Denso ignition parts identical to the factory specifications. The precise part number depends on the trim, market, and whether the vehicle uses direct or port injection. Always verify against official Honda data for your VIN.
Earlier generations and alternate engines
Older CR-Vs with different engines may use platinum or iridium plugs depending on the year and market. In practice, many engines from the Honda lineup default to NGK or Denso iridium/platinum plugs rated for long life. The best practice remains to confirm the exact part number from official documentation or a parts lookup tool.
Important note: Do not rely on a generic spark plug unless it matches the engine code and heat range specified for your CR-V. Mismatched plugs can affect performance and emissions.
How to identify and purchase the correct plugs
Here is how to determine the exact spark plugs for your CR-V and where to buy them.
To determine the exact plug for your CR-V:
- Check the owner's manual or the service section of Honda's website for your model year and market. Look for the recommended spark plug part number for your engine code.
- Inspect the current spark plug or its packaging for the part number; it often has the NGK or Denso code printed on the side.
- Record your engine code from the under-hood emission label or the vehicle identification label; common engines include the 1.5L turbo (L15B) and various 2.0–2.4L configurations depending on year.
- Use an online parts catalog or contact a Honda dealer with your VIN to pull the exact spark plug specification.
- When in doubt, buy OEM-equivalent plugs from NGK or Denso that match Honda’s specification for your engine. Ask for the exact heat range and thread size for your model.
The recommended approach is to rely on official sources or trusted aftermarket equivalents that specify compatibility with your engine code and year. Using the wrong heat range or plug type can cause misfires, reduced efficiency, or damage.
Choosing between NGK and Denso
Many Honda CR-V owners choose between NGK and Denso plugs. Both brands supply OEM-quality iridium or platinum plugs, and either will work if it matches Honda's specification for your engine. The decision often comes down to availability, price, and local service recommendations.
Some practical considerations when selecting between NGK and Denso:
- Ensure the plug matches the exact heat range and thread specification for your engine.
- Check local price, availability, and lead-time at your preferred retailer or dealer.
- Consider OEM-equivalent plugs for warranty coverage and dealer compatibility.
- Ask a technician about any known field service bulletins affecting your model year.
In practice, dealers and experienced technicians tend to favor OEM equivalents for reliability and warranty considerations. When shopping, verify the exact part number for your engine code to ensure compatibility, especially if you have a non-stock or European market version.
Summary
The Honda CR-V's spark plugs are engine- and year-specific. For modern CR-Vs, expect iridium long-life plugs from NGK or Denso, with the exact part number tied to your engine code and market. Always consult the owner's manual or a dealer/official parts catalog to confirm the correct plug and gap. If you provide your CR-V's model year and engine code, I can identify the exact part number and recommended replacement interval.
