    Answer: Denso SC16HR11 spark plugs require minimal maintenance. Regular inspection is recommended, especially if you notice performance issues. It's generally a good practice to check them during routine service intervals or at least once a year. If they show signs of wear or fouling, replacing them promptly will help maintain a well-functioning engine. Ensuring that your ignition system is working correctly is crucial for maximizing the lifespan of your spark plugs.
