do88 Front IC Radiator, BMW M2 M3 M4 G80 G82 G87 (S58)

Improve the performance of your 2021+ BMW G8X M2/M3/M4 with the do88 Front Intercooler Water Cooler, a radiator designed for optimal charge air cooling under demanding driving conditions.

Background

The S58 engine features a water-to-air charge air cooler connected to its own cooling system, which includes a heat exchanger (water cooler) mounted at the front of the car. This heat exchanger cools the system's water, which in turn cools the intake air as it flows through the charge air cooler.

Key features

• 39% larger core than original.
• 2-row core that is 48mm thick, providing an increased active cooling area of 9%.
• Quadruple-pass flow, meaning the water passes through the cooler four times instead of two as on the original cooler, ensuring maximum contact of the cooling water with all cooling area.
• Slightly taller cooling fins compared to original, 5mm instead of 4.4mm. This ensures continued good airflow to the engine radiator located behind this cooler, despite the increased thickness of the core.
• Full aluminum cooler with durable TIG-welded end tanks.
• Increased fluid volume (1.4 liters more) for optimal heat dissipation.
• Improve your BMW G8X M2/M3/M4 with our do88 cooler and unlock enhanced cooling efficiency and performance under demanding driving conditions.

Challenges with the S58 Charge Air Cooling System

Owners of tuned S58 engines often encounter the problem of rapid heat soak in the charge air cooling system, especially during track driving. High intake temperatures can cause the ECU to reduce power output, or even put the car into limp mode. The do88 Front Intercooler Water Cooler helps keep temperatures down and improve your car's reliability and performance.

Our Solution

The custom do88 cooler design began with a complete overhaul, prioritizing durability and performance. By removing plastic components in favor of robust aluminum for the end tanks, core, and CNC-machined ports, and by ensuring everything is TIG-welded, our cooler delivers durability and long-term performance. The introduction of a Quad pass design improves cooling, with the cooling water passing through the cooler's core four times for maximum efficiency. But do88's goal extends beyond mere durability. By increasing the core volume by 39% and the external tube area by 9%, while simultaneously integrating a Quad pass flow for the cooling water, the do88 cooler surpasses the original. This results in improved cooling capacity, thereby enhancing your car's performance.

Installation

The cooler is designed for easy installation with your BMW's factory components. It comes with custom stone chip guards to protect against debris. Our cooler fits both cars with automatic or manual transmissions, making it a versatile upgrade for all G8X M2/M3/M4 models.
