Step-by-Step Instructions

1. Locate the Spark Plugs

• Open the hood and locate the engine cover.
• Remove the engine cover by unlatching the clips or bolts.
• The spark plugs are located on top of the engine, typically in a row of four or six.

2. Remove the Ignition Coils

• Identify the ignition coils connected to the spark plugs.
• Use a 10mm socket or wrench to loosen the bolts securing the ignition coils.
• Carefully lift the ignition coils straight up to disconnect them from the spark plugs.

3. Remove the Old Spark Plugs

• Use a spark plug socket or wrench to unscrew the old spark plugs.
• Apply gentle force to avoid stripping the threads.
• If the spark plugs are stuck, use a penetrating lubricant or gently rock the socket back and forth.

4. Inspect the Old Spark Plugs

• Examine the old spark plugs for signs of wear or damage, such as:
• Worn or eroded electrodes
• Carbon buildup
• Fouling or glazing

5. Gap the New Spark Plugs

• Use a spark plug gap gauge to check and adjust the gap between the electrodes.
• The gap specification for Honda Odysseys varies depending on the model year and engine type. Refer to your vehicle’s owner’s manual for the correct gap.

6. Lubricate and Install the New Spark Plugs

• Apply a small amount of dielectric grease to the threads of the new spark plugs.
• Hand-tighten the new spark plugs into the cylinder head.
• Use a spark plug socket or wrench to tighten the spark plugs to the specified torque.

7. Reinstall the Ignition Coils

• Position the ignition coils over the spark plugs.
• Press down firmly to reconnect them.
• Tighten the bolts securing the ignition coils.

8. Reconnect the Battery

• Reconnect the negative battery terminal.

9. Start the Engine

• Start the engine and let it idle for a few minutes.
• Check for any leaks or unusual noises.

Recommended Frequency for Changing Spark Plugs

Honda recommends changing the spark plugs in your Odyssey every 105,000 miles or 7 years, whichever comes first. However, it’s important to note that driving conditions and the quality of the spark plugs can affect their lifespan. If you notice any signs of poor engine performance or increased fuel consumption, it’s advisable to inspect and replace the spark plugs sooner.

Benefits of Changing Spark Plugs

• Improved engine performance and responsiveness
• Reduced fuel consumption
• Lower emissions
• Extended engine life
• Reduced risk of engine damage
