NGK Spark Plug CR8EIB-10 4948, NG4948

Iridium IX Spark Plug - CR8EIB10 (4948)

Key Features:

• Iridium Electrode: The iridium center electrode is 25% smaller than platinum and just 1/4 the size of a conventional nickel electrode, making it stronger and harder for longer-lasting performance.
• Reduced Voltage Requirement: The ultra-small diameter (0.6mm) center electrode reduces the voltage requirement for ignition, helping to extend the life of the ignition system.
• Brighter and Stronger Spark: The fine wire electrode design and tapered cut ground electrode allow for a brighter, stronger spark, which enhances engine performance and efficiency.
• Enhanced Durability: The iridium electrode and platinum-tipped ground electrode provide excellent longevity, making this plug suitable for high-performance engines and demanding conditions.
• Anti-Corrosion Metal Shell: The new metal shell plating offers enhanced anti-corrosion qualities, ensuring reliable operation even in harsh environments.
