• High-Grade Silicon Steel Core: Provides superior magnetic induction for a stable and powerful high-voltage output.

• Germany-Imported Copper Wire: Premium enameled wire ensures excellent conductivity and resistance to internal short-circuiting.

【DOUBLE IRIDIUM SPARK PLUGS】

• Double Iridium Design: Features an iridium center electrode and a platinum/iridium ground chip for the highest melting point and extreme durability.

• Sensitive Ignition: Delivers faster and more consistent ignition jumps, resulting in improved throttle response and fuller combustion.

• Isostatic Ceramic Insulators: High-density ceramic prevents flashover and provides excellent thermal management under heavy loads.
