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.

Each end tank is constructed from high-grade aluminum for strength and durability. The TIG-Welded construction further increases the overall strength. Each top end tank includes a pre-plugged 1/8th NPT and each bottom end tank includes M16x1.5P ports for temperature sensors. The CSF radiators mount in the factory location and require no modifications or cutting.

Each radiator includes a 1.4 bar high pressure cap with an embossed CSF logo. High pressure radiator caps raise the boiling point of coolant. This helps protect the system from boiling over at higher operating temperatures. While the radiator is designed to keep the system from reaching such temperatures, it is always good to have extra protection for situations where the coolant gets too hot.
