Unlock more consistent performance from your 2019-2021 Mercedes-AMG GT63 and GT63S X290 with our GCA Performance High-Performance Intercooler/Heat Exchanger. Designed specifically for the demanding requirements of the 4.0L Twin Turbo V8 M177 engine, this upgrade improves thermal efficiency, reduces heat soak, and helps maintain stronger performance during aggressive driving and high-boost applications.

The factory cooling system can experience rising intake temperatures during repeated acceleration, spirited driving, or tuned setups. Our upgraded heat exchanger features an optimized high-efficiency core, increased fin density, and improved coolant capacity to provide superior heat dissipation and more consistent power delivery.

Engineered with a strategic internal flow path, this system minimizes pressure drop while maximizing cooling capacity. The reinforced aluminum construction and cast aluminum end tanks are designed to handle increased boost pressures while maintaining long-term durability.

Developed under our performance division, GCA Performance, this intercooler/heat exchanger is the ideal cooling solution for AMG enthusiasts looking to maximize the potential of their X290 GT63 or GT63S.
