CSF High-Performance all-aluminum auxiliary radiator for Mercedes-Benz M157 5.5L V8 biturbo models, spanning the E63, CLS63, S550/S560/S600, SL-Class, G63, GL63, ML63 and more. Beyond lowering engine water temperatures, it serves as the heat-exchange medium for the air-to-water charge-air coolers, reducing intake air temperatures and extending the heat-soak threshold. It uses a 2-row 68mm core with CSF's exclusive B-Tube technology versus the OEM 1-row 42mm core, with 6.5mm multi-louvered fins, 100% all-aluminum TIG-welded construction, CNC-machined brackets and OEM-style quick-connect fittings. A detachable rock guard guards against debris and core punctures. CSF recommends two units to replace both left and right OEM radiators.
