It runs a water-to-air charge cooler, and the charge air temperature is set by how well that coolant circuit sheds heat. From the factory the circuit is small, and on a hot day or a second hard run it saturates — coolant temperature climbs, intake temperature follows, and the ECU pulls timing and boost to protect the engine. The car does not break, it just quietly gets slower, and most owners put it down to the weather.\u003c\/p\u003e\n\u003cp\u003eThis kit attacks that directly. The factory front heat exchanger is replaced with a far larger aluminium core, and a second radiator is added in the wheel arch to raise total coolant volume and surface area. More coolant takes longer to heat, and more surface area sheds it faster, so the circuit recovers between runs instead of stacking heat.\u003c\/p\u003e\n\u003ch3\u003eKey Features:\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eOversized Front Heat Exchanger\u003c\/strong\u003e\u003cbr\u003eA full-width aluminium core replacing the factory unit, mounted at the original locations in front of the main radiator.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAuxiliary Side Radiator\u003c\/strong\u003e\u003cbr\u003eA second core mounted in the wheel arch, adding coolant capacity and surface area the standard circuit simply does not have.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAll-Aluminium Construction\u003c\/strong\u003e\u003cbr\u003eAluminium cores and end tanks throughout, TIG welded, with machined hose barbs rather than crimped fittings.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAttacks Heat Soak, Not Peak Power\u003c\/strong\u003e\u003cbr\u003eThe gain is consistency.
