The 42mm 2-Row aluminum core increases the fluid capacity of the radiator by over 1 gallon (3.8L). A thicker core, second cooling row, and increased fluid capacity drastically improves the amount of heat the system can absorb and dissipate. CSF's Exclusive B-Tube Technology increases the heat transfer by approximately 15% over regular oval welded tubes. In addition, the super-efficient multi-louvered fins maximize airflow through the core for the best possible cooling performance. The TIG-Welded 100% All Aluminum construction increases the overall strength of the radiator. This improves durability and longevity so you can be confident it will hold up to hard driving conditions. The CSF radiator mounts in the factory location and requires no modifications or cutting.
CSF manufactures the most advanced and efficient radiator in the industry for your WRX. CSF uses innovative tube and fin technologies with industry-leading testing methods to maximize airflow and heat dissipation.
