Description
Unlock peak cooling performance with the AMS Performance Heat Exchanger designed exclusively for the BMW G87 M2, G80/G81 M3, and G82/G83 M4 with the S58 engine. This Limited Edition model featuring the iconic M Color Logo blends engineering excellence with visual flair, delivering a performance upgrade that’s track-tested, race-proven, and built to outperform the competition.
Unlike generic aftermarket options, the AMS Heat Exchanger is crafted from CNC-machined billet 6061 T6 aluminum with a bespoke, high-efficiency dual-pass core designed to maximize thermal performance while preserving OEM-like fitment. With a 35% larger core volume and double the coolant capacity of the stock unit, this drop-in upgrade drastically reduces intake air temperatures (IATs), minimizes heat soak, and ensures consistent power output—even under the harshest driving conditions.
Designed by the Snailworks® Engineering Team, the precision-engineered radiused inlet and outlet fittings significantly reduce pressure drop and promote optimal coolant flow throughout the intercooler system. With no cutting, trimming, or drilling required, installation is a straightforward bolt-on process using factory mounting points.
Validated through dyno testing, street evaluations, and on-track abuse—including events like Gridlife and Super Lap Battle with pro racer Jackie Ding—the AMS Heat Exchanger consistently outperformed OEM and aftermarket competitors alike. Real-world testing recorded intercooler air outlet temps as low as 112.8°F, compared to 116.4°F for OEM, and 120.2°F for the leading competitor, proving this unit delivers when it matters most.
Whether your G8X is factory stock or heavily modified, give your S58-powered BMW the cooling it deserves.
