Supplier's note

  1. Three Technical Breakthroughs:

    • Aluminum Liner Core: With 60% higher thermal conductivity than copper, it reduces coolant temperature by 15°C faster.
    • Optimized Fin Pitch: 20% denser fins than industry standards boost heat dissipation by 25%.
    • Triple-Layer Coating: The Pro model’s corrosion resistance exceeds OEM specs by 300%, enabling use in marine or industrial environments.

  2. Version Selection Guide:

    • Base Model: Ideal for standard road use in A3 sedans (e.g., daily commuters needing OEM replacement).
    • Advanced Model: Best for high-performance variants like Quattro or convertible models requiring 20% faster cooling.
    • Pro Model: Tailored for heavy-duty applications (e.g., race-prepped A3 Limousines) where extreme durability and efficiency are critical.

With the Pro’s 4.5 bar pressure rating, you can safely handle turbocharged engines generating 30% more horsepower. Pair its corrosion-resistant coating with off-road vehicles to prevent coolant leaks in harsh terrains.
