BMW Auxiliary Radiator - do88 WC-440
Upgrade the performance of your 2021+ BMW G8X M2/M3/M4 engine with the do88 Performance Auxiliary radiators!
The S58 Engine Cooling System
The S58 engine features a cooling system with three frontal radiators, one large central radiator and two smaller auxiliary radiators located in front of each wheel. Tuned engines produce significantly more heat, making it challenging to maintain optimal engine temperatures during intense street, track, or drag strip driving. The OE auxiliary radiators have slim cores and plastic tanks, which are not ideal for tuned cars. Upgrading these auxiliary radiators is will help to ensure proper engine temperature.
Our Solution
Fortunately, the design space available for the auxiliary radiators allows for both increased frontal surface area and core thickness on both sides of the car. The OE radiator is identical for both sides, and our do88 Performance Radiators are designed to be drop-in replacements for both left and right sides. We offer them as a pair because upgrading just one radiator isn't as effective as upgrading both simultaneously. Our Performance Auxiliary Radiators provide enhanced cooling capacity to prevent heat soaking.
Installation
The installation is simple, as our radiators come with CNC-machined mounting brackets and OE-style “Quick Connect” inlet/outlet connections. The OE rock guard can be easily attached to our radiators for protection against small rocks and road debris.
Key Features:
- Larger core volume than the original equipment (OE), 43% larger.
- 2-row core that is 48mm thick, this provides an increased active cooling area by a whole 13%.
- Full aluminum construction, complete with durable TIG-welded end tanks.
- Increased fluid capacity (X,X liter more) for optimal heat dissipation.
