With enthusiasts, tuners, and race teams pushing these cars further than anyone originally anticipated, this High-Performance All-Aluminum Radiator completes the full cooling suite alongside CSF's well-known heat exchanger and auxiliary radiator products for this platform.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eWith more and more people pushing the limits of the Supra and its BMW siblings, the factory radiator has started showing its limitations. Increased boost and upgraded turbos generate significantly more heat, and combined with the heat exchanger mounted in front of the radiator, engine coolant temperatures can climb too high, especially during track use, where it can trigger limp mode. CSF's replacement uses a 2-row, 42mm aluminium core built around their exclusive B-Tube technology, increasing heat transfer surface area by approximately 15% over regular tubes for genuine dual liquid laminar flow. This is a true drop-in fit, using CNC-machined mounting brackets and OEM-style connections, with no modifications required to install.\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 location and connections.
