NGK Iridium/Platinum Spark Plug (IZFR6K-11)

NGK Laser Iridium spark plugs are a well-built option for a wide range of vehicles, including many Acura and Honda models like the Accord, CR-V, and TL. These plugs are designed to offer a good balance of performance and how long they last. They are an actual OE or equivalent replacement, meaning they meet the original equipment standards for your car.

The center electrode on these plugs is made from an iridium alloy, which is significantly harder than platinum and can handle the high temperatures found in modern engines. This fine wire design helps ensure a stable spark for consistent ignition. The insulator is made of pure alumina silicate ceramic, which is strong and helps transfer heat away from the plug. For improved resistance to corrosion and seizing, the plugs feature a trivalent metal plating. Many also include a platinum pad on the ground electrode for even wear, especially in distributorless ignition systems.

This set comes with four spark plugs, which is the correct quantity for most 4-cylinder engines. The copper core inside helps remove excess heat, and triple seals are used to prevent leaks. These are a solid option if your vehicle originally came with fine wire iridium alloy plugs.
