Description
Keep your BMW G8X M2 (G87), M3 (G80), and M4 (G82) running at optimal temperatures with the do88 Performance Auxiliary Radiator. Designed specifically for S58 engines, this upgrade is essential for high-performance applications, whether on the street, track, or drag strip. With an increased core volume, improved heat dissipation, and full aluminum construction, this auxiliary radiator prevents overheating and ensures long-term engine reliability.
Why Upgrade Your BMW’s Auxiliary Radiator?
The S58 engine features a triple-radiator cooling system, including one large central radiator and two smaller auxiliary radiators located near each front wheel. When tuning your BMW for increased horsepower, the factory auxiliary radiators struggle to dissipate the additional heat effectively, leading to heat soak and reduced engine efficiency.
The OEM auxiliary radiators have:
- Thin cores that limit cooling efficiency.
- Plastic tanks that can become weak over time.
- Limited cooling capacity, especially for tuned engines.
The do88 Performance Auxiliary Radiators solve these problems by offering superior cooling performance, ensuring that your engine stays within safe temperature ranges, even under extreme driving conditions.
