Product Details

The CSF 8131 is a high-performance triple-pass heat exchanger engineered specifically for B58 and B48-powered BMW F3X and F2X chassis vehicles. This upgraded heat exchanger significantly reduces intake air temperatures (IAT) to maximize engine performance while providing faster heat soak recovery compared to the factory unit.

Key Features:

  • Triple-pass design for superior cooling efficiency and heat dissipation
  • Integrated rock guard protection in silver finish shields core from road debris
  • High-density bar-and-plate core construction for maximum heat transfer
  • Direct bolt-on replacement for factory heat exchanger
  • Engineered for B58 and B48 turbocharged engines in F2X and F3X chassis
  • Maintains consistent IAT under demanding driving conditions
  • CSF manufacturing quality with precision TIG-welded end tanks

This heat exchanger is essential for enthusiasts running increased boost levels, track driving, or seeking consistent performance in high-temperature environments. The triple-pass configuration forces coolant through the core three times, dramatically improving heat rejection compared to stock single or dual-pass designs.
