CSF Performance Radiator – Toyota Supra A90 / BMW G-Series

OVERVIEW

CSF is the largest and most popular manufacturer of A9X Supra and BMW B58 cooling systems. With enthusiasts, tuners and race teams pushing these cars further than anyone anticipated, CSF completed the cooling suite with this High-Performance All-Aluminum Radiator for the A9X Supra and BMW G-Series.

The radiator uses a 2-row, 42mm ultra-high-performance core with cooling tubes built on CSF's exclusive B-Tube technology, which increases heat transfer by roughly 15% over a conventional tube. The core carries new 5mm tall ultra-efficient multi-louvered fins for maximum surface area contact, and construction is 100% all-aluminum TIG-welded with CNC-machined mounting brackets and OEM-style inlet and outlet connections.

Every unit is individually leak and pressure tested and finished with a 1-hour hand-polished mirror finish. Installation is true plug-and-play in the factory location and requires absolutely no modifications.
