DESCRIPTION
Upgrade engine cooling components with the do88 Aluminum Radiator. WC-430 fits BMW M2/M3/M4 S58 (G80/G82/G87).
Improve the performance of your 2021+ BMW G8X M2/M3/M4 with the do88 Front Intercooler Radiator, a radiator designed for optimal charge air cooling under demanding driving conditions.
Background
The S58 engine has a water-to-air charge cooler paired with a heat exchanger (water radiator) in the front of the car. This radiator cools the water flowing through the charge air cooler, dissipating heat from the charge air before it enters the engine.
Challenges of the S58 Charge Air Cooling System
Owners of tuned S58 engines often encounter 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 Radiator helps to keep temperatures down and improve reliability and performance.
Our Solution
The custom do88 radiator design began with a total overhaul, prioritizing durability and performance. By eliminating plastic components in favor of sturdy aluminum for the end tanks, core, and CNC-machined ports, and ensuring everything is TIG-welded, our cooler provides durability and long-term performance. The introduction of a Quad pass design improves cooling, with the coolant passing through the cooler's core four times for maximum efficiency.
By increasing the core volume by 39% and the external tube area by 9%, while integrating a Quad pass flow for the coolant, the do88 cooler goes beyond the original. This results in improved cooling capacity, thereby enhancing performance.
Installation
The do88 cooler is designed to be easily mounted with your BMW's factory components. It comes with custom rock guards to protect against debris. Fits both automatic and manual transmission cars, making it a versatile upgrade for all G8X M2/M3/M4 models.
Kit Contents:
- 39% larger core than original.
- 2-row core that is 48mm thick, providing an increased active cooling area by 9%.
- Quadruple-pass flow allows water to pass through the cooler four times instead of two, maximizing contact with the cooling area.
- Slightly higher cooling fins (5mm vs 4.4mm), ensuring good airflow to the engine radiator despite the increased core thickness.
- Full aluminum construction, complete with durable TIG-welded end tanks.
- Increased fluid capacity (1.4 liters more) for optimal heat dissipation.
Upgrade your BMW G8X M2/M3/M4 with our do88 radiator and unlock improved cooling efficiency and performance under demanding driving conditions.
