NGK Laser Iridium Double Fine Electrode Iridium Spark Plug Heat 6 Box of 4 (DFH6B-11A)

These NGK Laser Iridium spark plugs are a direct replacement for many Lexus models, including the GS300, IS250, and LS460. They feature a double fine electrode design with an iridium-tipped center electrode and a platinum pad on the ground electrode, which helps ensure a consistent and stable spark for optimal engine performance and longevity. This setup is designed to provide improved ignitability and durability compared to standard platinum plugs.

The pure alumina silicate ceramic insulator offers excellent strength and heat transfer, helping to prevent overheating. For added protection against corrosion and seizing, the plugs have a trivalent metal plating. The copper core inside the insulator aids in removing heat from the plug itself, further contributing to its reliable operation. These are built to OE standards, meaning they're made to perform just like the original plugs your Lexus came with.

Because these are designed as OE replacements, they fit right in without any modifications needed. They are sold in a box of four, which is what most vehicles will need for a full tune-up, but always check your specific vehicle's requirements.
