The CSF all-aluminum radiator for 1999–2002 Nissan R34 GT-R is a drop-in high-performance unit engineered to control heat from high-output RB engines. The 2-row 42mm core raises coolant capacity and cooling surface, while CSF's B-Tube Technology boosts heat transfer by roughly 15%. TIG-welded aluminum tanks, pre-plugged sensor ports, a 1.4 bar cap and OE fan shroud mounts provide strong, no-modification installation; note later R34 models require different fan shroud hardware.
