A spark plug is a cylindrical device that is threaded at both ends with electrodes at the center. The function of a spark plug is to produce an electric current in order to ignite the air-fuel mixture in an internal combustion engine.

Your Hyundai Sonata can be equipped with different types of spark plugs, depending on the engine type. Here I have compiled a list of the best spark plugs for the Hyundai Sonata. These are either OEM spark plugs or the best alternatives. In most cases, they do not need to be re-gapped.

When it comes to choosing spark plugs, there are a few things you need to take into account. The first is the type of engine your Sonata has. Two types of engines are available in the Sonata: Gasoline Direct Injection (GDI) and Nu Engine (NE). If you’re not sure which type of engine your Sonata has, check the owner’s manual or ask your mechanic.

Next, you need to consider the spark plug’s size. Spark plugs come in a variety of sizes, so it’s important to choose one that will fit your car’s engine. Again, consult your owner’s manual or mechanic to find out what size spark plug you need.

Finally, you need to decide on the material of the spark plug. Spark plugs are made from a variety of materials, including copper, platinum, iridium, and more. Each material has its own set of benefits and drawbacks. For example, copper spark plugs are the most affordable but don’t last as long as other types of spark plugs. Platinum and iridium spark plugs, on the other hand, cost more, but they last longer.

When to Replace Spark Plugs?

How often you need to replace your spark plugs depends on your type of spark plug. Copper spark plugs, for example, need to be replaced every 20,000 to 30,000 miles. Platinum and iridium spark plugs can last up to 100,000 miles. However, it’s best to consult your owner’s manual or mechanic to determine how often you should replace your particular spark plug.

How Often Should You Change Spark Plugs Hyundai Sonata?

Do you know that you need to change your spark plugs every 60,000-90,000 miles? Spark plugs are a crucial part of your car. They help ignite the fuel in your engine. If the spark plugs are dirty or worn down, they will not be able to fire as well and can cause damage such as misfires, rough idling, and more. Even better, you will notice an increase in acceleration and horsepower after changing the spark plugs in your car.
