Supplier's note

  1. Technical Breakthroughs:

    • Iridium Electrodes: 40% smaller gap vs. platinum, enabling faster ignition.
    • Ceramic Insulation: Reduces heat transfer by 25%, prolonging electrode life.
    • Metal Alloy Body: 30% stronger than traditional designs, resisting vibration fatigue.

  2. Version Selection Guide:

    • Base Model: Ideal for routine maintenance in stock engines (e.g., daily drivers).
    • Advanced Model: Suited for modified engines (e.g., turbocharged or high-compression setups).
    • Pro Model: Designed for racing or extreme conditions, with triple the industry-standard corrosion resistance.

With the Pro version’s 1400°C heat tolerance, you can safely handle high-octane fuels and sustained high RPMs. Pair its iridium core with the ceramic insulator to ensure consistent ignition even under extreme load.
