Supplier's note

  1. Breakthrough Features:

    • Dual-material construction: Combines metal strength with plastic thermal resistance for longer lifespan.
    • Enhanced sealing: Blue/green O-rings reduce emissions by 25% vs. standard designs.
    • Nozzle precision: 0.01mm tolerance ensures 15% better fuel atomization than generic injectors.

  2. Version Selection Guide:

    • Base Model: Ideal for routine maintenance in standard Kia 2.4L engines.
    • Advanced Model: Choose for modified engines needing higher fuel flow (e.g., turbo setups).
    • Pro Model: Engineers selected for racing or heavy-duty use cases require the 400 bar pressure rating and 200,000-cycle seals.

With the Pro version’s 400 bar tolerance, you can safely handle high-performance fuel pumps while maintaining leak-free operation. Pair its stainless-steel nozzle with synthetic fuels to maximize efficiency in extreme conditions.
