What makes iridium spark plugs different from platinum?

Iridium is a much harder and more durable metal than platinum, with a higher melting point. This allows for a finer center electrode, which requires less voltage to create a spark and results in a more consistent and stable spark over a longer lifespan.

Do these spark plugs come with anti-seize pre-applied?

These spark plugs feature trivalent metal plating for superior anti-corrosion and anti-seizing properties. However, it's always a good practice to refer to the vehicle manufacturer's service manual for specific installation recommendations, which may include applying anti-seize compound.

What is the benefit of the platinum pad on the ground electrode?

The platinum fine wire tip on the ground electrode helps ensure even wear, especially in modern distributorless ignition systems. This contributes to maintaining optimal spark performance and plug longevity throughout its service life.

Product Details

In this box, you get four NGK Laser Iridium spark plugs, part number DILKR6C11. These are designed to be a direct replacement for your vehicle's original equipment, offering a great balance of performance and how long they last. They fit a range of vehicles, including models like the Hyundai Santa Fe Sport, Kia Optima, and Hyundai Sonata.

The center electrode on these plugs is tipped with iridium, which is a very hard metal that stands up to high temperatures and wear much better than platinum. This means you get a consistent, strong spark over a longer period. The insulator is made from pure alumina silicate ceramic, which helps transfer heat away from the plug and also provides solid strength. For added protection against corrosion and seizing, the metal plating is trivalent.

These plugs also feature a platinum pad on the ground electrode, which helps them wear evenly, especially in modern ignition systems. The copper core inside helps manage heat, and triple seals are used to prevent any leaks. They are a solid option if your vehicle originally came with DFE iridium alloy plugs.
