The insulators are manufactured with a ULTRA-TITE ceramic material that provides a secure seal against the cylinder head, minimizing the risk of detonation and reducing exhaust gas leakage.

Additionally, the Iridium XP spark plugs feature a unique, tapered insulator design that ensures proper gap maintenance and prevents the gap from changing due to thermal expansion. This results in a more consistent and stable spark, leading to improved combustion efficiency and overall engine performance.

TheNGK BCDP-7166-4199791 Iridium XP Spark Plug Kit is also designed to meet or exceed OEM specifications for ignition energy, resistance to fouling, and durability. This ensures that your Lexus LS400 or SC400 engine will continue to perform at its best, providing you with a smoother, more responsive driving experience.

Installing theNGK Iridium XP spark plugs is a straightforward process that can be done at home or by a professional mechanic. Each spark plug comes with a detailed installation guide and a protective boot to shield the electrode from contaminants and moisture.
