Why AMS?
Engineered for Enthusiasts, Built to Win
The AMS Performance Heat Exchanger is a masterpiece of engineering, designed to outshine generic aftermarket options. Unlike competitors’ low-quality universal cores and welded sheet metal, AMS uses a high-efficiency, dual-pass core with optimized fin height and density for unparalleled heat transfer. The radiused coolant fittings reduce pressure drop, ensuring smoother, more efficient flow—a small but critical detail that sets AMS apart. This precision craftsmanship ensures your S58 engine stays cool under the most demanding conditions, from 200 MPH roll races to hot-lap track sessions.
Real-World Dominance
Tested in dyno sessions, street runs, and competitive motorsport events like Gridlife and Super Lap Battle, the AMS Heat Exchanger consistently outperforms. While the OEM system struggles with heat soak and competitors falter under pressure, AMS delivers lower IATs, reduced heat soak, and sustained power delivery. In head-to-head testing, it achieved a 16°F coolant temp reduction compared to the leading aftermarket unit, proving its superior thermal efficiency. Whether your G8X is stock or pushing 1000+ horsepower, this heat exchanger is the ultimate upgrade for reliability and performance.
