What is the primary benefit of the 60mm thick core?

The 60mm thick core significantly increases the radiator's surface area. This allows for more efficient heat exchange, helping to keep engine temperatures lower, especially under heavy load or during spirited driving.

Does this radiator require modifications for installation?

No, this do88 radiator is designed as a direct fit replacement for the factory unit. It utilizes the original mounting points, simplifying the installation process without the need for custom fabrication.

What other parts should I consider replacing when installing a new radiator?

It's a good practice to inspect and potentially replace coolant hoses, clamps, and the thermostat while the radiator is out. This helps ensure the entire cooling system is in good condition and prevents future leaks or failures.

Product Details

This do88 radiator is built with a core that measures 60mm thick, offering a significant increase in surface area compared to the stock unit. This larger core is designed to work with the side-mount intercooler setup common on the 2015-2020 BMW M3 and M4 (F8X chassis). The increased cooling capacity helps manage engine temperatures, especially under demanding driving conditions where the stock system can struggle to keep up.

Constructed with all-aluminum end tanks and a high-efficiency core, this radiator is well-built to handle the stresses of performance driving. The all-aluminum construction not only aids in heat dissipation but also offers good resistance to corrosion. It's designed as a direct replacement for the factory radiator, meaning it fits into the existing mounting points without requiring modifications, simplifying the installation process. This makes it a solid option for owners looking to improve their vehicle's cooling system performance without extensive custom work.

When installing this radiator, it's a good idea to inspect all your coolant hoses and connections for any signs of wear or leaks. Replacing old hoses while you have the radiator out can prevent future issues and ensure your new cooling system operates at its best. This radiator is a key component for maintaining optimal engine temperatures, particularly if your M3 or M4 sees track use or aggressive street driving.
