For a 2011 Hyundai Sonata, it's generally recommended to change the spark plugs every 60,000 to 100,000 miles, depending on the type of spark plugs used. If your Sonata has platinum or iridium plugs, they may last closer to the 100,000-mile mark. Regular inspection is also advised, as driving conditions and engine performance can affect their lifespan. Always refer to your owner’s manual for specific recommendations.
