Wagner Tuning Performance Intercooler Kit for Mercedes-AMG GT / GTS / GTC / GTR M178 V8

AMG GT Cooling Upgrade • M178 4.0L Bi-Turbo V8

Wagner Tuning Performance Intercooler Kit — AMG GT / GT S / GT C / GT R (C190)

Crush heat soak and keep your power consistent pull after pull. This drop-in, water-to-air intercooler upgrade delivers dramatically better charge-air cooling with minimal pressure drop — perfect for spirited street driving and track days.

The Mercedes-AMG GT M178 uses an indirect (water-to-air) charge-air cooling circuit. Under repeated hard pulls, intake temps rise quickly, the ECU pulls power, and the car feels softer the longer you drive. The Wagner Tuning Performance Intercooler Kit replaces the factory intercoolers with a larger, more efficient core designed for the demands of the AMG GT / GT S / GT C / GT R.

Result: lower IATs, reduced heat soak, and more repeatable power — especially on tuned cars or track setups.
