A pair of full-aluminum auxiliary radiators for the 2020+ Toyota GR Supra 3.0L (B58), replacing the slim stock core and plastic end tanks with TIG-welded aluminum construction built for street, track and strip use. The core thickness grows to 1.57 inches for a 30% increase in core volume, while the updated tube-and-fin design expands external fin surface area by 180% for maximum heat dissipation. Strutted tubes run through the core for added stability against breaks and leaks, and the set is finished in polished aluminum.
