BMW G80, G82, G87 / M3, M4, M2 (S58) Front Mount Radiator

BMW G80/G82/G87 M3/M4/M2 (S58) Front Mount Radiator

Take your BMW S58 cooling system to the next level with this High-Performance Front Mount Radiator, engineered to significantly improve charge cooling efficiency, reduce heat soak, and maintain consistent performance during spirited driving, track days, and high-horsepower applications.

The S58 engine utilises a sophisticated water-to-air charge cooling system, where a front-mounted heat exchanger cools the coolant circulating through the integrated charge cooler. Under repeated acceleration, hot climates, or tuned applications, the factory system can become heat soaked, causing intake temperatures to rise and the ECU to reduce engine performance.

This upgraded Front Mount Radiator has been engineered to overcome these limitations by increasing cooling capacity, coolant volume, and overall thermal efficiency. Manufactured from premium all-aluminium construction with TIG-welded end tanks and CNC-machined fittings, it delivers exceptional durability while providing substantially improved cooling performance over the factory unit.

Whether your BMW is stock, Stage 1, Stage 2, or running upgraded turbochargers, this radiator helps maintain lower intake temperatures, more consistent power delivery, and increased reliability under demanding conditions.

Key Features

39% Larger Core Volume

Features a radiator core with 39% greater core volume than the factory unit, providing substantially improved cooling capacity.

48mm Dual-Row Aluminium Core

Utilises a 48mm thick dual-row aluminium core for maximum heat dissipation while maintaining excellent airflow through the cooling stack.

Quad-Pass Coolant Design

Features an advanced quad-pass internal flow design, allowing coolant to circulate through the core four times instead of two, maximising heat transfer efficiency.

Increased Cooling Surface Area

Provides approximately 9% greater active cooling surface area compared to the factory radiator for improved thermal performance.

Increased Coolant Capacity

Holds approximately 1.4 litres more coolant than the factory radiator, helping reduce heat soak during repeated hard driving.

Premium All-Aluminium Construction

Manufactured from high-quality aluminium with fully TIG-welded end tanks and CNC-machined fittings for outstanding durability and corrosion resistance.

Includes Protective Rock Guards

Supplied with custom protective mesh guards to help protect the radiator core from stone chips and road debris.

Direct Bolt-On Installation

Designed as a direct replacement using the factory mounting locations with no permanent vehicle modifications required. Compatible with both manual and automatic transmission models.
