Spark Plugs for 2018 Hyundai Sonata: FAQ
What type of spark plug is recommended for a 2018 Hyundai Sonata?

How often should spark plugs be replaced on a 2018 Hyundai Sonata?
Hyundai typically recommends replacement around 60,000 to 100,000 miles, but the exact interval depends on your engine and driving conditions. Refer to your owner's manual.

Many iridium plugs come pre-gapped, but it's wise to verify the gap with a tool. The correct gap is specified in your owner's manual or on the plug packaging.
