Aggressive track sessions in the F8X chassis often lead to heat soak as the factory auxiliary radiators reach their thermal limits. The CSF 8258 replaces the plastic-shrouded factory units with a 100% all-aluminum TIG-welded design that eliminates the failure-prone OE mounting pod. By integrating the mounting points directly into the modular tank design, CSF increased the core size by 6.4% and tank volume by 10% within the same factory footprint.

Key Features

  • 2-Row 42mm high-performance core with B-Tube technology
  • Ultra-efficient 6.5mm tall multi-louvered fins for maximum surface area
  • 100% all-aluminum TIG-welded construction for durability
  • Integrated detachable rock guards to prevent puncture from road debris
  • Multi-fit design works for both the left and right side positions
  • OEM-style quick-connect inlet and outlet for a secure fit
  • Satin black finish for a stealthy appearance behind the grilles
  • Individually leak and pressure tested
  • 2-year limited warranty
