The CSF 7231B is the satin black version of CSF's all-aluminum high-performance radiator for the 1999-2002 Nissan Skyline R34 GT-R with the turbocharged 2.6L RB26 inline-6. It uses a 2-row 42mm core with 75 cooling tubes, 76 multi-louvered 6.5mm fin rows, and CSF's B-Tube Technology. It is 100 percent TIG-welded aluminum with aluminum end tanks in place of the OEM plastic tanks, pre-plugged 1/8 inch NPT and M16 sensor ports, and a 1.4 bar high-pressure cap. It fits both early and late R34 GT-Rs, though late models use different fan-shroud mounting hardware, and it does not fit non-GT-R R34 models.
