This is CSF's all-aluminum Triple-Pass radiator for the MQB-platform VW Golf/GTI/Golf R and Audi A3/S3/TT. The triple-pass flow structure routes coolant across the core three times before exiting for the lowest possible outlet temperatures. It uses a 2-row, 42mm dual core with CSF's exclusive B-Tube Technology and 6.5mm multi-louvered fins, plus an all-aluminum race-style drain plug. It is a drop-in fit that accepts all OEM components, including quick-connect hoses, AC condenser, mounting brackets, and fan shroud.
