CSF Performance Front Mount Heat Exchanger for Select Mercedes-Benz 2011-2019 (5.5L) #8197

Fits select 2011-2019 Mercedes-Benz CLS63 AMG, E63 AMG, SL63 AMG, SL65 AMG, and SLS AMG (5.5L).

Standard factory heat exchangers often utilize plastic tanks and restricted cores that struggle to manage the thermal demands of the high-output AMG 5.5L V8 bi-turbo engine, especially during spirited driving or increased boost levels. The CSF High-Performance Heat Exchanger (MPN 8197) replaces the OEM plastic/aluminum unit with an all-aluminum, TIG-welded solution designed to maintain lower intake air temperatures and prevent heat soak.

Engineered for maximum thermal efficiency, this unit features CSF’s proprietary B-Tube technology. This design uses a thin-walled, multi-channel tube that increases the surface area contact by approximately 15% compared to standard oval tubes. With 40% more tubes than the factory core, this exchanger delivers a 300% increase in flow area and twice the cooling performance. The 23mm super-high efficiency core is paired with ultra-efficient 5mm multi-louvered fins to ensure rapid heat dissipation.
