Once the car is tuned, that small heat exchanger can't shed the extra heat, intake temperatures rise during repeated pulls, and power drops. The do88 WC-400 replaces it with an all-aluminum unit that has 80 percent more core volume and runs the coolant through four passes instead of two.\u003c\/p\u003e\n\u003cp\u003eThe two-row, 48 mm core adds about 36 percent more cooling surface, while a 5 mm fin height keeps air flowing to the engine radiator behind it. The tanks are TIG-welded and the unit holds about 2.6 liters more coolant than stock. It has mounting points for the OE transmission cooler and both factory rock guards. The factory plastic radiator mounting frame does need trimming to fit.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAll-aluminum construction with TIG-welded end tanks\u003c\/li\u003e\n\u003cli\u003eCore volume 80 percent larger than OE\u003c\/li\u003e\n\u003cli\u003eTwo-row core, 48 mm thick; about 36 percent more cooling surface\u003c\/li\u003e\n\u003cli\u003eQuadruple-pass coolant flow (OE: two-pass)\u003c\/li\u003e\n\u003cli\u003e5 mm fin height (OE: 4.4 mm)\u003c\/li\u003e\n\u003cli\u003eHolds about 2.6 L more coolant than OE\u003c\/li\u003e\n\u003cli\u003eMounting points for the OE transmission cooler and both OE rock guards\u003c\/li\u003e\n\u003cli\u003eReplaces OE 17118666811 (BMW), 16400-WAA03 (Toyota)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1 × do88 performance heat exchanger (front intercooler radiator)\u003c\/li\u003e\n\u003cli\u003e2 × brackets (for the oil cooler and radiator guard)\u003c\/li\u003e\n\u003cli\u003e6 × M5 screws\u003c\/li\u003e\n\u003cli\u003e6 × zip-ties\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRequired extras:\u003c\/strong\u003e charge-cooler circuit coolant — the do88 unit holds about 2.6 L more than stock.
