Unlock the full performance potential of your BMW G8X M2, M3, or M4 with the AMS Performance Heat Exchanger (Black Logo Edition), engineered for maximum cooling efficiency in even the most extreme driving conditions. Whether you're tracking your car, pushing triple-digit speeds in high-heat environments, or simply demanding the most reliable power output from your S58 engine, this heat exchanger is the ultimate bolt-on upgrade. Designed as the largest drop-in heat exchanger available for the G8X platform, it significantly enhances the thermal stability of your air-to-water intercooler system without requiring any modifications.
Featuring a 35% larger core volume and dual-pass design, this heat exchanger drastically reduces coolant temperatures and intake air temps (IATs), allowing your engine to maintain consistent performance under demanding conditions. Built from billet 6061 T6 aluminum with precision CNC-machined end tanks and AMS-spec high-density core fins, this unit delivers unmatched durability and heat transfer efficiency. Its installation is seamless and straightforward, utilizing OEM mounting points with no cutting, drilling, or trimming required.
Unlike many generic or ill-fitting alternatives, the AMS Performance Heat Exchanger integrates cleanly with your factory setup and is designed with optimal fluid dynamics in mind. The proprietary radiused coolant inlet and outlet fittings reduce pressure drop while improving flow, maximizing the cooling efficiency of your entire intercooler system.
This performance cooling solution has been rigorously tested on the street, dyno, and racetrack—including validation in competition by professional racing driver Jackie Ding. The result is a proven, track-tested product capable of reducing outlet coolant temperatures by 16°F compared to leading aftermarket alternatives.
