Description
The CSF High-Performance All-Aluminum Radiator offers enhanced cooling for Audi B8 S4/S5 and various other 3.0L and 3.2L Audi models. Engineered for both street and track performance, this radiator is constructed with a 2-row, 42mm core that employs CSF's proprietary B-Tube Technology. This design expands the heat transfer surface area by about 15% compared to traditional "O" type tubes, providing "dual liquid laminar flow" for superior thermal efficiency.
Complementing the B-Tubes are ultra-efficient, multi-louvered fins with a 6.5mm height, precisely aligned to maximize airflow and heat dissipation. The radiator features CNC-machined "quick-connect" inlet and outlet connections, along with CNC-machined brackets and fittings, ensuring a durable, precise fit. It also includes an upgraded plate-type transmission oil cooler, with a plug provided for manual transmission applications. The radiator boasts a smooth satin finish and an all-aluminum race-style drain plug.
This radiator is designed as a true "drop-in fit," requiring no modifications for installation and accepting all attaching OEM components, including hoses, the AC condenser, mounting brackets, and fan shroud. It is compatible with a wide range of Audi models, including the B8 A4 Quattro (2013-2014 Supercharged 3.0L V6 Manual, 2009-2012 3.2L V6 Auto/Manual), B8 A5 (2015-2016 Supercharged 3.0L V6 Auto/Manual, 2008-2010 3.2L V6 Auto), B8 A5 Quattro (2012-2016 Supercharged 3.0L V6 Auto/Manual, 2008-2011 3.2L V6 Auto), C7 A6 (2016 Supercharged 3.0L V6 Manual, 2012-2018 A6 Quattro Supercharged 3.0L V6 Auto/Manual, 2012-2016 A6 Quattro Turbo Diesel 3.0L V6), C7 A7 Quattro (2012-2018 Supercharged 3.0L V6, 2014-2016 Turbo Diesel 3.0L V6), 8R Q5 (2010-2017 Turbo Diesel 3.0L V6, 2013-2017 Supercharged 3.0L V6, 2009-2012 3.2L V6), B8 S4 (2010-2016 Supercharged 3.0L V6 Auto/Manual), B8 S5 (2010-2017 Supercharged 3.0L V6 Auto/Manual), 8R SQ5 (2014-2017 Supercharged 3.0L V6), and Porsche Macan models (2017-2018 GTS Turbocharged 3.0L V6, 2015-2021 S Turbocharged 3.0L V6, 2015-2021 Base Turbocharged 3.0L V6, 2015-2018 Base Turbocharged Diesel 3.0L V6).
