Supplier's note

  1. Three Technical Breakthroughs:

    • Aluminum Die-Casting: Reduces weight by 30% vs. copper-brass alternatives while maintaining structural integrity.
    • Optimized Fin Geometry: Achieves 25% lower pressure drop compared to industry-standard designs.
    • OE-Exact Fitment: Eliminates adapter requirements, ensuring leak-proof sealing and reduced installation time.

  2. Version Selection Guidance:

    • Base Model: Ideal for standard VW applications with stock engine setups.
    • Advanced Model: Recommended for modified engines or frequent high-temperature environments (e.g., towing).
    • Pro Model: Triple corrosion resistance (vs. industry norms) makes it perfect for marine or industrial machinery. With its 4.5 bar pressure rating, it withstands extreme conditions while maintaining peak cooling efficiency.
