The 2006 Honda CR-V uses four spark plugs, one for each of its four cylinders.
In more detail, the model year typically features a 2.4-liter inline-four engine. With four cylinders, there are four spark plugs in the engine. The ignition system usually uses a separate coil for each cylinder (coil-on-plug), pairing with the corresponding spark plug. This means routine maintenance often targets all four plugs at once to ensure even performance and reliability.
Engine layout and spark plug count
Key facts about the spark plug setup are summarized here.
- Engine configuration: 2.4-liter inline-four with four cylinders
- Spark plugs: four in total — one per cylinder
- Ignition system: typically coil-on-plug per cylinder
- Replacement intervals: copper plugs ~30,000–60,000 miles; platinum/iridium plugs commonly 60,000–100,000 miles, depending on the exact part and driving conditions
Taking these points together, the 2006 CR-V's spark plug count is four, reflecting its four-cylinder layout and per-cylinder ignition design.
Maintenance considerations
For maintenance, refer to the owner's manual for the recommended plug type and replacement interval. When replacing, use the correct torque and follow OEM guidelines. If necessary, consult a mechanic to confirm the exact plug specification for your vehicle's VIN, as there can be minor variations by market or revision.
Summary
The 2006 Honda CR-V uses four spark plugs in its four-cylinder 2.4-liter engine—one per cylinder. Replacement timing varies by plug material, but many owners replace all four together during routine maintenance to preserve balanced performance.
