High-Efficiency Cooling for Subaru WRX/STI

Upgrade your Subaru's cooling system with the CSF High-Performance All-Aluminum Radiator. Designed specifically for the 2002-2007 Subaru Impreza WRX and STI, this radiator features a sleek black finish that looks as good as it performs. Whether you are running a high-boost street setup or competing on the track, this unit ensures your engine remains at peak operating temperatures.

Why Choose CSF B-Tube Technology?

CSF’s proprietary B-Tube Technology sets this radiator apart from the competition. By using a 'B' shaped tube design, CSF maximizes the surface area for cooling while allowing for a lighter, thinner aluminum construction. This design improves heat dissipation efficiency by approximately 15% compared to standard 'O' type radiator tubes.

  • Core: 2-Row high-performance core
  • Finish: Durable black powder coat
  • Fitment: 2002-2007 Subaru WRX/STI and 2004-2006 Baja
  • Performance: Superior thermal management for modified engines
  • Durability: Brazed seams for maximum structural strength

Don't let heat soak limit your Subaru's performance. This direct-fit radiator is engineered to handle the increased heat loads of turbocharged engines, providing the reliability you need for spirited driving. Upgrade your cooling system today with the best parts available at GGCRACING.
