CSF Audi B8 S4 & S5 High Performance All-Aluminum Radiator

CSF’s High-Performance 2-Row Radiator is complete with precise CNC machined fittings and brackets to allow ease of installation in the complex plastic housing system. It also includes an OEM-style wire harness bracket system to secure the harness that runs across the top of the radiator.

In addition to CSF’s high-performance radiator core design, CSF has added an upgraded plate-type transmission oil cooler to the left side tank for improved transmission cooling in vehicles with automatic transmissions (comes pre-plugged for use in manual transmission vehicles).

Special thanks to David, Kevin, and Jeremy from ECS Tuning for helping us with development of this new and exciting radiator – just in time to keep you cool for Summer 2021. See the full fitment list and buy-it-now link below.
