BMW G8X M2/M3/M4 S58 Heat Exchanger by AMS Performance
Whether you’re doing laps at the track, making 200 MPH roll racing pulls, or just driving in a hot climate, the AMS Performance BMW G8X Heat Exchanger for the M2, M3, and M4 is engineered to keep your intake temps down and your power output up.
Designed as a high performance, drop-in solution, this heat exchanger is the largest and most effective unit available on the market, delivering superior cooling capacity without the need for any modifications.
The 3.0L S58 twin-turbocharged engine in your G8X BMW uses an air-to-water intercooler system, where coolant is used to manage intake air temperatures. While the factory setup may work under mild conditions and stock horsepower levels, it quickly becomes a limiting factor during aggressive driving — causing heat soak and reducing power. The AMS Heat Exchanger solves this problem with a 35% larger core and dramatically more efficient design built for enthusiasts who demand the most from their vehicle.
