NGK Laser Iridium Long Life Spark Plugs (IZFR6K-11S)

The iridium-tipped center electrode on these NGK Laser Iridium spark plugs is six times harder than platinum, offering excellent durability and a consistently stable spark. These are designed as an OE equivalent replacement, meaning they meet the original equipment manufacturer's standards for your 2006-2011 Honda Civic. The pure alumina silicate ceramic insulator helps with heat transfer and provides superior strength, while the 98 percent pure copper core aids in heat removal to prevent overheating.

NGK also includes a platinum pad on the ground electrode for even wear, which is especially beneficial in distributorless ignition systems. For added protection, these plugs feature trivalent metal plating to resist corrosion and seizing, and triple seals to prevent leaks. If your Civic came with fine wire iridium alloy plugs from the factory, these are the recommended replacement to maintain performance and longevity.
