Description
Elevate the cooling efficiency and reliability of your BMW S58-powered M3 and M4 with the Untd. Performance Aluminum Radiator, engineered specifically for the G80/G82 platform (2021+). The factory radiator can struggle to manage heat during aggressive driving, track sessions, and tuned high-boost conditions, leading to heat soak and inconsistent performance.
This high-efficiency aluminum radiator delivers significantly improved cooling capacity, faster heat dissipation, and superior durability—ensuring stable temperatures and consistent performance for street, track, and competitive motorsport applications.
Built to handle the elevated thermal demands of tuned S58 engines, it provides the cooling overhead needed for Stage 2, Stage 3, and hybrid-turbo builds while maintaining OEM fitment.
Key Features
High-Efficiency Aluminum Construction
Crafted from full aluminum with TIG-welded end tanks, this radiator offers superior strength, heat transfer, and reliability compared to the OEM plastic tank design.
Increased Cooling Capacity
Upgraded core density and optimized fin geometry improve coolant flow and heat dissipation, keeping temperatures stable during long pulls, track sessions, and high-load conditions.
Supports High-Boost & Tuned Applications
Designed for S58 engines running elevated boost, aggressive mapping, or upgraded turbos. Prevents heat soak and maintains consistent power delivery.
Improved Reliability Under Extreme Conditions
Aluminum tanks and reinforced welds eliminate cracking and expansion issues common in factory plastic units, ensuring long-term durability.
Direct Bolt-On Fitment
Precision-engineered to fit the OEM mounting points with factory-style connections for hoses, sensors, and shrouds—no modifications required.
