What is the importance of proper maintenance of spark plugs for engine operation and efficiency on Toyota Yaris?

Spark plug maintenance is key for engine efficiency. Use plugs specified in the Vehicle Emissions Control Information label or Owner's Handbook. If the engine is in good condition, spark plugs usually don't need attention between scheduled maintenance. To replace, remove the ignition coils in vehicles with a direct ignition system. Accessing the deeply recessed plugs requires a 16 mm spark plug socket and extension bar. Check each plug's condition upon removal. The electrode gap is crucial and should be set to the specified value. Before installing, ensure the plug's connector sleeves are tight and clean. Tighten the plugs to the specified torque with a torque wrench and spark plug socket, then refit the ignition coils and air cleaner.
