Supplier's note

1. Technical Breakthroughs:

   • Ceramic Insulator: Reduces heat transfer by 30% compared to standard porcelain, preventing pre-ignition.
   • Iridium Electrodes: 20x harder than platinum, extending service life to 150,000 miles.
   • Laser-Welded Design: Eliminates gap erosion, maintaining optimal spark performance across -40°C to +1,200°C.

2. Version Selection Guidance:

   • Base Model: Ideal for standard LPG engines (e.g., 2.5L Toyota Kluger) requiring basic OE replacement.
   • Advanced Model: Recommended for high-output engines (e.g., 3.5L FJ Cruiser) needing enhanced heat resistance.
   • Pro Model: Best for turbocharged or racing applications (e.g., 4.6L Ford engines) where triple-certified durability is critical.

Example Use Case: The Pro version’s 1,200°C heat resistance enables safe operation in supercharged Toyota trucks, paired with iridium’s corrosion resistance to withstand LPG moisture. This combination reduces maintenance costs by 40% over 100,000 miles.
