High-performance all-aluminum radiator for the Audi B8 platform, fitting S4, S5, A4/A5 Quattro, A6/A7 Quattro, Q5/SQ5 and the Porsche Macan, for street and track use. The 2-row 42mm dual core uses CSF's exclusive B-Tube technology, which raises heat-transfer surface area about 15% over standard tubes for dual laminar flow and better cooling efficiency, paired with 6.5mm multi-louvered fins. It installs as a true drop-in accepting all OEM components including quick-connect hoses, AC condenser, brackets and fan shroud, with CNC-machined quick-connect fittings and an all-aluminum race-style drain plug.
