{"product_id":"csf-vag-mqb-triple-pass-radiator","title":"CSF VAG MQB Triple Pass Radiator","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eWhen modifying MQB platform vehicles, most attention goes toward chasing power, with the right mix of intakes, exhausts, intercoolers, and software, a nearly 30% increase in output is genuinely within reach. What often gets overlooked is the factory water cooling system, which now has to manage not just increased engine heat but the additional heat from the integrated exhaust manifold in the cylinder head. In demanding situations like track driving, it's not unusual for these engines to run well above the 90°C shown on the coolant gauge, reaching up to 130°C.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eCSF's Triple-Pass Radiator addresses this directly. The 2-row, 42mm core uses CSF's exclusive B-Tube technology, increasing tube efficiency by approximately 15% over regular oval tubes for greater strength and lighter, more efficient heat transfer. A genuine triple-pass flow structure routes coolant across the core three times before it exits, rather than just once, for the lowest achievable outlet temperature, paired with 6.5mm wind-tunnel-optimised multi-louvered fins for maximum surface area contact. In rigorous testing on a 500hp track-driven Mk7 Golf R, this upgrade kept engine water temperatures below 100.5°C and oil temperatures under 125°C, a substantial improvement over the OEM setup's spikes exceeding 140°C. Further testing in hotter ambient conditions and on more demanding circuits confirmed consistently strong results.\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, hoses, and fittings.
