Keep your intake temps cool and your S58 running strong.

Upgrade your G8X M-car’s charge air cooling system with the do88 Front Intercooler Radiator – a high-performance, all-aluminium replacement designed to eliminate heat soak and improve reliability under track and spirited road use.

Why Upgrade?

Heat Soak is the S58’s Weak Point

The BMW S58 engine relies on a water-to-air charge cooling system, with a front-mounted water radiator feeding coolant to the intercooler integrated in the inlet manifold. On tuned or hard-driven G8X models, the system is prone to heat soak, resulting in higher intake temps, reduced power, or even limp mode activation.

A True Motorsport Cooling Upgrade

do88’s solution replaces the factory unit with a 2-row, 48mm thick all-aluminium core featuring a Quad-pass flow design — meaning the coolant flows through the radiator four times instead of two. The result? Maximum cooling contact and reliable performance when it matters most.
