Improve the performance of your 2021+ BMW G8X M2/M3/M4 engine with do88 Performance auxiliary radiators!
The S58 Engine Cooling System
The S58 engine features a cooling system with three front radiators, a large central radiator, and two smaller auxiliary radiators located in front of each wheel. Tuned engines produce significantly more heat, making it difficult to maintain optimal engine temperature during intense street, track, or drag strip driving. OE auxiliary radiators have thin cores and plastic tanks, which are not ideal for tuned cars. Upgrading these auxiliary radiators will help ensure proper engine temperature.
Our Solution
Fortunately, the design space available for auxiliary radiators allows for both increased frontal surface area and core thickness on both sides of the car. The OE radiator is identical on both sides, and our do88 Performance radiators are designed to be a replacement for both the left and right sides. We offer them in pairs because upgrading just one radiator isn’t as effective as upgrading both at once. Our high-performance auxiliary radiators provide increased cooling capacity to prevent heat buildup.
Installation
Installation is simple, as our radiators feature CNC-machined mounting brackets and OE-style “Quick Connect” inlet/outlet connections. The OE rock guard can easily be attached to our radiators to protect them from small rocks and road debris.
Key features include:
Larger core volume than original equipment (OE), 43% larger.
The 48mm thick, 2-row core provides 13% more active cooling area.
All-aluminum construction, complete with durable TIG-welded end tanks.
Increased fluid capacity (X.X liters more) for optimal heat dissipation.
