The CSF 8154 is a high-performance heat exchanger that replaces the factory 1-row, 25mm front heat exchanger on B58 and B48 equipped Supra and BMW G-Series cars, lowering intake air temperatures and speeding heat soak recovery for tuned and upgraded turbo builds. It uses a 2-row core with CSF's B-Tube technology and 5mm tall multi-louvered "Track-Spec" fins in 100% aluminum TIG-welded construction. A unique tank design lets the larger core drop into the OEM cooling system housing with OEM style quick connect inlet and outlet fittings. It includes a metal rock guard, CNC machined mounting brackets, and billet transmission oil cooler mounts for a plug-and-play install.
