NGK Laser Iridium Spark Plug Box of 4 (ILZFR6D11)

NGK Laser Iridium spark plugs are a solid option for replacing your worn-out plugs, offering a good blend of performance and how long they last. These are actual OE or equivalent replacements, meaning they're built to the same standards as what came on your car from the factory. They fit a range of vehicles, including models like the BMW 325i, 530xi, and X3.

The center electrode uses an iridium alloy, which is notably durable and helps maintain a stable spark. This fine wire design is perfect for today's modern engines. You'll also find a platinum pad on the ground electrode in many of these plugs, which helps them wear evenly, especially in distributorless ignition systems. The pure alumina ceramic insulator helps with heat transfer, and the trivalent metal plating on the threads helps prevent corrosion and seizing during installation and removal. A copper core also aids in heat removal, keeping the plug from getting too hot.

This set comes with four spark plugs, which is what most 4-cylinder and some 6-cylinder engines will need. Always double-check how many spark plugs your specific engine requires before ordering.
