Under sustained hard driving — especially on track — this system heat-soaks quickly, causing the ECU to pull timing or reduce power to protect the engine. The do88 Front Intercooler Radiator is a direct-fit, larger-capacity replacement for the factory heat exchanger, designed specifically to solve this problem without any modification to the surrounding components.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCore volume:\u003c\/strong\u003e Up to 80% larger core volume than the factory unit, depending on platform\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Dual-row, 48mm-thick core (compared to the OE single\/thinner core), full aluminum construction with durable TIG-welded end tanks\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow design:\u003c\/strong\u003e Quad-pass coolant flow — water passes through the core four times instead of two, maximizing contact with the cooling surface\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFins:\u003c\/strong\u003e Slightly taller 5mm cooling fins (vs. the OE 4.4mm) to maintain good airflow to the main engine radiator behind it despite the thicker core\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacity:\u003c\/strong\u003e Increased coolant capacity (roughly 1.4-2.6L more, depending on platform) for better sustained heat dissipation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1x do88 front intercooler radiator (heat exchanger) for the selected platform\u003c\/li\u003e\n\u003cli\u003eRock guards \/ mounting hardware as applicable\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eIncludes mounting points for the OE transmission cooler and factory rock guards — no permanent modification to surrounding brackets is required.\u003c\/li\u003e\n\u003cli\u003eOn the B58 Gen 2 \/ Supra fitment, some trimming of the factory plastic radiator mounting frame is necessary to clear the larger core (see installation instructions).\u003c\/li\u003e\n\u003cli\u003eOn the S58 G8X fitment, the unit is compatible with both automatic and manual transmission cars and includes custom rock guards.\u003c\/li\u003e\n\u003cli\u003eThis is a heat exchanger (front radiator) only — it works alongside the factory or an upgraded \u003ca href=\"https:\/\/x58cartel.com\/products\/do88-charge-cooler-manifold-bmw-b58-s58-amp-toyota-supra\"\u003edo88 Charge Cooler Manifold\u003c\/a\u003e\/intercooler core, not in place of it.\u003c\/li\u003e\n\u003cli\u003ePart of a complete do88 front cooling stack — pair with the \u003ca href=\"https:\/\/x58cartel.com\/products\/do88-transmission-cooler-bmw-b58-amp-toyota-supra\"\u003edo88 Transmission Cooler\u003c\/a\u003e and a do88 Auxiliary Radiator (\u003ca href=\"https:\/\/x58cartel.com\/products\/do88-auxiliary-radiator-bmw-b58-s58-amp-toyota-supra\"\u003eB58 Gen 2\/Supra\u003c\/a\u003e or \u003ca href=\"https:\/\/x58cartel.com\/products\/do88-auxiliary-radiator-bmw-s58-g8x-m2-m3-m4\"\u003eS58 G8X\u003c\/a\u003e).\u003c\/li\u003e\n\u003cli\u003eProfessional installation is recommended;
