The opportunity to develop this radiator for the 3.0L TFSI supercharged V6 was brought to CSF by a European Audi specialist who approached them directly to ensure their own 2020 B8 S4 giveaway car build was kept cool. CSF used that real-world development and marketing vehicle to make sure fitment for this genuinely complex radiator was a true drop-in fit, requiring no modifications to install.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe 2-row, 42mm high-performance core uses CSF's exclusive B-Tube technology. Rather than a regular oval \"O\"-shaped tube, a specially engineered \"B\"-shaped tube is carefully formed and brazed over the seam, increasing heat transfer surface area by approximately 15% over regular tubes while allowing for thinner, lighter aluminium construction that's genuinely stronger than a normal welded design. Ultra-efficient 6.5mm tall multi-louvered fins maximise surface area contact, and precise CNC-machined fittings and brackets handle the ease of installation into this platform's genuinely complex plastic housing system, including an OEM-style wire harness bracket to secure the harness running across the top of the radiator. A genuinely practical addition: an upgraded plate-type transmission oil cooler is built into the left side tank for improved cooling on automatic transmission vehicles, and comes pre-plugged for straightforward use on manual transmission cars.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eWorks with:\u003c\/strong\u003e OEM mounting points and wire harness routing.
