NGK Laser Iridium Spark Plug (ILZKR7D8)

NGK is well-known for making reliable ignition components, and their Laser Iridium spark plugs are a prime example. If you're looking to replace your spark plugs, these offer a solid combination of performance and how long they last. They're built to meet the original equipment standards for your vehicle, meaning they're tested to ensure they work right and hold up over time.

The center electrode uses an iridium alloy, which is about six times harder than platinum, giving it excellent durability. This tough material helps maintain a consistent spark, even in today's high-tech engines. The insulator is made from pure alumina silicate ceramic, which is strong and helps manage heat effectively. Plus, the copper core inside helps dissipate heat, preventing the plug from getting too hot. For vehicles with distributorless ignition systems, you'll often find a platinum pad on the ground electrode to help it wear evenly.

These plugs also come with trivalent metal plating, which helps prevent corrosion and makes them easier to remove down the road. They're designed with triple seals to prevent any leaks. If your vehicle originally came with fine wire iridium alloy plugs, these are a great choice for a replacement.
