do88 Front Intercooler Radiator – BMW M3 / M4 / M2 Competition (F8x, S55)

OVERVIEW

The S55 cools its charge air with water, and that water is cooled by two small radiators: a large one in front of the center cooling pack and a small one ahead of the right front wheel. How cold those radiators keep the water decides intake air temperature, and intake air temperature decides peak power. The do88 WC-350 replaces the larger, front-mounted one.

do88 3D-scanned an M3 Competition's front cooling pack and made the core 166 mm taller and 5 mm thicker while leaving enough airflow for the components behind it. Core volume is 75 percent larger and frontal area 48 percent larger. Paired with the do88 side-mounted radiator, they measured intake air 5 °C cooler at 240 km/h. It's a drop-in fit on the factory lines.
