Part #: 7231

The 2-Row 42mm core greatly not only increases the fluid capacity of the radiator, but also improves the cores ability to dissipate heat. 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 performance. More cooling rows also improve the overall efficiency of the radiator. More cooling tubes means more surface area for the coolant's heat to dissipate from.

CSF manufactures the most advanced and efficient radiator in the industry for your R34 Skyline. CSF uses innovative tube and fin technologies with industry-leading testing methods to maximize airflow and heat dissipation.
