NGK Iridium/Platinum Spark Plug Box of 4 (SILZKR7B11)

NGK Laser Iridium spark plugs are a solid option for many vehicles, offering a good balance of performance and longevity. These are actual OE replacement plugs, meaning they're built to the same standards as what came on your car from the factory. They feature a fine-wire center electrode made of an iridium alloy, which has a very high melting point and is significantly harder than platinum, helping to ensure a consistent spark and durability over time. The pure alumina ceramic insulator helps with heat transfer, keeping the plug from overheating, and the copper core also aids in heat removal. Plus, the trivalent metal plating on the outside helps prevent corrosion and seizing, making them easier to remove down the road.

The design includes a raised platinum pad on the ground electrode, which helps with even wear, especially in modern distributorless ignition systems, and further improves spark performance. These plugs are recommended for vehicles that originally came with OE iridium alloy plugs, and they feature triple seals to prevent any gas leakage. You'll get a box of four plugs, which is what most 4-cylinder engines will need.
