CSF High-Performance all-aluminum radiator for VAG MQB platform cars, fitting the VW Golf R, Jetta GLI, Beetle and Audi A3/S3 and TT/TTS. It runs a 2-row 42mm dual core with CSF's exclusive B-Tube technology, a specially formed B-shaped tube seam-brazed for strength that raises heat-transfer surface area roughly 15% over conventional round tubes while allowing thinner, lighter aluminum. Ultra-efficient multi-louvered 6.5mm fins are aligned per application to maximize airflow. CNC-machined brackets, fittings and quick-connect inlet/outlet plus an all-aluminum race-style drain plug make it a drop-in fit that accepts all OEM attaching components, including the AC condenser and fan shroud. Finished in black for a stealth look.
