Most Honda CR-Vs with modern iridium- or platinum-tipped spark plugs are designed for replacement around 105,000 miles (170,000 kilometers) under normal driving. Always verify the exact interval for your year and engine in the owner’s manual or via the Honda maintenance minder.
What affects the replacement interval
Several factors determine when you should replace spark plugs. The plug type (iridium/platinum versus copper), engine design, and your driving conditions all influence the recommended interval. The Honda Maintenance Minder system will alert you when it's time, which can differ from the generic mileage guideline.
Here are the typical intervals you might see listed by Honda, depending on plug type and usage.
- Iridium or platinum spark plugs: replacement around 105,000 miles (170,000 km) under normal driving, according to Honda's maintenance schedule for most late-model CR-Vs.
- Copper spark plugs: replacement roughly 30,000–60,000 miles (50,000–97,000 km). Note: Copper plugs are uncommon on newer CR-V models, but may appear on older trims or legacy engines; confirm the plug type in your manual.
- Severe driving conditions: frequent short trips, extreme temperatures, heavy towing, or dusty environments can shorten the interval. The Maintenance Minder may prompt earlier replacement in these cases.
Bottom line: For most modern CR-Vs with iridium or platinum plugs, plan for about 105,000 miles; if yours uses copper plugs, expect earlier replacement; always follow the manufacturer’s maintenance minder and your specific owner's manual for the exact schedule.
Signs you may need a spark plug change sooner
If you notice performance issues or abnormal engine behavior, it may be time to inspect or replace the spark plugs even if you’re not yet at the scheduled mileage.
- Rough idling or engine misfires, especially at idle or during acceleration.
- Reduced acceleration or power and hesitation when you press the gas.
- Lower fuel economy or carbon deposits on the spark plugs after inspection.
- Check Engine Light or misfire codes (for example, P0300 range) indicating ignition problems.
- Difficult starting or frequent stalling, particularly when the engine is hot or cold.
If you observe these symptoms, have a mechanic diagnose the issue. Worn or fouled plugs can cause further engine damage or reduced efficiency, so addressing them promptly is wise.
What to expect during a spark plug replacement
Whether you DIY or have a shop perform the replacement, here’s a typical outline of what happens and what to watch for.
- Tools and parts: the correct spark plugs for your engine (check the gap specification). A torque wrench is used to reach the specified torque. Some models require particular torque values; consult the service manual or a shop.
- Procedure: disconnect the negative battery, access the spark plugs (coils or wire leads may need to be removed), clean the area, remove old plugs, check old plug condition, install new plugs by hand to seat, then tighten to the manufacturer’s torque spec. Reinstall coil packs, reconnect electrical connections, and reconnect the battery. Clear any diagnostic codes if needed and test the engine after replacement.
- Notes and cautions: avoid overtightening; some engines use anti-seize agents but many modern engines do not require anti-seize and applying it can affect torque. If you’re unsure, have a professional perform the work.
Expect labor costs to vary by model year and whether you have a turbocharged engine, which may use specialized plugs; always get a written estimate before work.
Summary
In short, for most modern Honda CR-Vs, spark plugs are designed for long life and are typically replaced around 105,000 miles under normal driving. The exact interval can differ by engine type and plug material, and the Honda Maintenance Minder may signal an earlier or later replacement. Always consult your owner’s manual and use the maintenance minder as your primary guide. If you notice symptoms of wear, have the plugs inspected promptly to avoid further engine problems.
What kills spark plugs quickly?
Pre-ignition can lead to heat building up in the combustion chamber causing the spark plugs to fail. In addition, if the cooling system isn't functioning correctly, it can cause the engine and spark plugs to overheat. This overheating can lead to the spark plug's electrode wearing out faster.

Which CRV year to stay away from?
The first CR-V of the 21st century sees an increase in engine-related issues and the beginning of a series of recalls for defective airbags (the notorious Takata airbag recall). The recall affected numerous model years (mostly 2002-2015), so always check this out if you're buying a used CR-V.
