do88 additional cooler suitable for BMW B58 G-Series / Toyota GR Supra A90

Increase the performance of your B58 Gen 2 engine with the do88 Performance additional water coolers!

The B58 engine cooling system
The B58 engine features a cooling system with three front radiators, a central main radiator and two smaller auxiliary radiators in front of each wheel. Tuned engines produce significantly more heat, making it difficult to maintain optimal engine temperatures during intense street and track driving. The OE auxiliary radiators have small radiator nets and plastic end tanks that are not ideal for tuned cars. Upgrading these auxiliary radiators will help ensure proper engine temperatures.

Our solution
Fortunately, the design space available for the auxiliary radiators allows for an increase in both the frontal area and mesh thickness on both sides of the car. The OE radiator is identical for both sides, and our do88 performance radiators are designed as replacements for both the left and right sides. We sell these in pairs because upgrading just one radiator is not as effective as upgrading both at the same time. Our performance auxiliary radiators offer improved cooling capacity to prevent overheating. Key features include:

• XX% larger water cooler core volume than the original equipment (OE).
• Double row water cooler mesh with a thickness of 40mm, which increases the cooling surface by XX%.
• All aluminum construction, complete with durable TIG welded end tanks.
• Increased liquid volume for optimal heat dissipation.

installation
Installation is easy as our radiators come with CNC machined mounting brackets and OE style "Quick Connect" inlet/outlet connections. The OE stone guard can be easily fitted to our radiators to provide protection against small stones and road debris.
