Solution

1. Review Manufacturer Specifications

Consult the owner’s manual for the specific model year for detailed maintenance intervals.
For the 2012-2017 Toyota Camry, the recommended spark plug replacement interval is typically every 120,000 miles for models equipped with the 2.5L 4-cylinder engine and 60,000 miles for the 3.5L V6 engine.

2. Inspect Spark Plugs

Remove the ignition coil or spark plug wires, taking care to label them for reinstallation.
Use a spark plug socket and ratchet to remove each spark plug from the cylinder head.
Examine each spark plug for signs of wear, such as excessive carbon buildup, electrode erosion, or damage.

3. Replace Spark Plugs

If replacement is necessary, ensure you have the correct type of spark plugs specified for your engine (iridium or platinum, as specified).
Apply a small amount of anti-seize compound to the threads of the new spark plugs, if recommended.
Torque the new spark plugs to the manufacturer's specifications, typically around 13-15 lb-ft.

4. Reinstall Components

Reattach the ignition coils or spark plug wires to their respective plugs.
Ensure all connections are secure and that there are no loose wires.
