CSF High-Performance All-Aluminum Radiator for 1999-2002 Nissan GT-R (R34) - 42mm 2-Row - Satin Black (7231B)

Fits 1999-2002 Nissan Skyline GT-R (R34). The CSF High-Performance All-Aluminum Radiator (7231B) is engineered to solve the cooling limitations of the factory unit during spirited driving or track sessions, offering a direct drop-in replacement with no modifications required.

This radiator features a 42mm, 2-row ultra-high-performance core utilizing CSF's exclusive B-Tube technology. Unlike standard oval tubes, the B-Tube design uses a reinforced structure that increases heat transfer surface area by approximately 15%. Combined with 6.5mm multi-louvered fins, this unit maximizes airflow and thermal dissipation. The 100% TIG-welded aluminum construction and satin black finish provide both durability and a stealthy aesthetic for the R34 engine bay.
