Rather than sourcing a separate radiator and oil cooler as two components, this genuinely integrated design simplifies both the parts list and the install.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe core uses CSF's exclusive B-Tube technology, a specially engineered \"B\"-shaped tube carefully formed and brazed over the seam, increasing heat transfer surface area by approximately 15% over regular tubes for genuine dual liquid laminar flow, while allowing for thinner, lighter aluminium construction that's actually stronger than a normal welded design. High-efficiency, multi-louvered fins are precisely aligned and wind-tunnel tested for maximum heat rejection. The built-in oil cooler comes complete with a GReddy thermostatic sandwich plate, which regulates oil flow to the cooler based on temperature rather than running the oil through the cooler constantly, and two -10 forged right-angle fittings are included for a clean, properly routed installation.\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 hose connections.
