do88 Front Intercooler Radiator, BMW G-Serie / Toyota GR Supra A90
Upgrade your B58 Gen 2 engine’s cooling system with the do88 Performance Front Mount Heat Exchanger, engineered for drivers who demand consistent power delivery on both road and track. The B58 platform, used in vehicles such as the Toyota GR Supra MK5, BMW M340i, M440i, and Z4 M40i, is well known for its impressive performance, but its factory charge air cooling system is prone to rapid heat soak under demanding conditions. High intake air temperatures force the ECU to pull timing or reduce power, leaving enthusiasts frustrated with inconsistent results. The do88 heat exchanger directly solves this issue by dramatically increasing cooling efficiency, ensuring your engine performs at its best when it matters most.
This premium unit delivers 80% more core volume than stock and features a dual-row, 48mm thick design that boosts cooling surface area by 36%. Its quad-pass layout maximizes coolant exposure to the core, while the larger 5mm fin height balances increased cooling capacity with airflow efficiency. Built entirely from aluminum with TIG-welded end tanks, this heat exchanger offers durability and long-lasting performance, even under extreme conditions. With 2.6 liters of extra coolant capacity, the do88 unit provides exceptional heat dissipation, reducing intake temperatures and preventing ECU-induced power cuts.
Installation is straightforward, as the heat exchanger is designed to integrate with OE components such as the transmission cooler and rock guards, though minor trimming of the OEM radiator mounting frame is required. Whether you are tracking your car or simply enjoying spirited road driving, the do88 Front Mount Heat Exchanger ensures your B58 engine maintains peak power with confidence and reliability.
