Supplier's note

  1. Key Breakthroughs:

    • The Pro Model’s 1,400°C resistance enables stable operation in heavy-duty trucks (e.g., Fortuner), outperforming industry benchmarks by 20%.
    • The Advanced Model’s magnetic alignment tool reduces installation time by 30% for technicians.
    • All versions use a ceramic core, cutting heat loss by 15% compared to traditional glow plugs.

  2. Version Selection Guide:

    • Base Model: Ideal for standard Toyota/Lexus diesel vehicles (e.g., Corolla Cross) with routine usage.
    • Advanced Model: Recommended for PHEV owners (e.g., RAV4 PHEV) needing extended service life and faster installation.
    • Pro Model: Best for commercial fleets (e.g., Hilux 4WD) requiring extreme durability and high-altitude performance.

With the Pro Model’s 25,000-hour lifespan, you can reduce replacement costs by 40% for heavy-duty applications. Pair its high-temperature tolerance with Toyota’s 3.0L diesel engines to achieve smoother cold starts in sub-zero environments.
