This charge cooling circuit runs on its own separate coolant loop, combining two parallel-connected radiators and a pump, the larger one positioned in front of the centre cooling module, and a smaller one located in front of the right-side wheel arch. Lowering the water temperature in this circuit translates directly to lower charge air temperatures, making high-performance radiators genuinely important for maintaining low, stable IATs during hard driving.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThis is the larger, centre-module radiator in that system, and do88's redesign delivers a genuinely substantial upgrade, a \u003cstrong\u003e75% larger core volume\u003c\/strong\u003e and \u003cstrong\u003e48% larger frontal surface area\u003c\/strong\u003e than the factory unit, using a high-efficiency core with 7mm multi-louvered fins. Across do88's entire testing programme for this platform, peak power was directly tied to how well IATs were controlled, making this radiator a foundational upgrade rather than a nice-to-have. Real-world testing, measured during full-throttle 0-240km\/h acceleration runs at an airstrip under identical same-day conditions, confirmed a \u003cstrong\u003e5°C reduction in post-intercooler air temperature\u003c\/strong\u003e (34°C versus 39°C stock) with this radiator fitted.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eWorks with:\u003c\/strong\u003e OEM cooling lines, genuine drop-in installation.
