CSF 8132 Cooling Radiator QUADRUPLE PASS DSG for VAG MQB

With over fifty years of experience in radiator manufacturing, CSF is the obvious choice when it comes to keeping your Audi A3/S3 engine cool and performing at its peak. Designed for track-day or track use, this high-performance all-aluminum radiator is a must-have for both high-performance street cars and race cars that require additional cooling in motorsport applications. This radiator features a 2-row core with CSF's exclusive "B-Tube" technology: Unlike traditional "O" style radiator oval tubes, CSF uses specially designed "B" shaped tubes. These B-tubes are carefully formed and then seam-soldered to seal them. CSF can use thinner and lighter aluminum material (with greater cooling efficiency) because this design is actually stronger than traditional "O" style welded tubes. The design (inlet opening in the middle of the tube, seam-soldered) increases the surface area of the tubes' heat exchange by approximately 15% compared to traditional tubes – the efficiency of two smaller tubes compared to one larger tube under the same space constraints. With the B-tube, "dual laminar flow" can be achieved. CSF also uses hyper-efficient fin stock that is carefully and precisely aligned to maximize airflow through the radiator core. The fin characteristics are carefully measured and calculated for each application and tested for maximum heat dissipation efficiency in a wind tunnel laboratory.

The CSF radiator for the Audi A3/S3 is a true "drop-in fit" design, requiring no modifications for installation. OE-style mounting brackets are CNC-machined and welded for maximum strength. The inlet/outlet ports are designed to match the OEM ports, so you can use OEM or aftermarket hoses. Trust the cooling experts at CSF for the most efficient, high-quality, and reliable radiators.
