Garrett 2015+ BMW M3/M4 (F80 M3 / F82 F83 M4) Air/Water Performance Intercooler -Black

The Garrett Powermax Performance Intercooler (888883-6002) is designed specifically for BMW F80/F82/F83 models equipped with the S55 3.0L twin-turbo I6 engine. This air-to-liquid intercooler features a high-efficiency bar-and-plate core that is 47% larger than the factory unit, significantly improving cooling capacity.

Designed for a direct-fitment installation, the unit incorporates a dual-pass coolant flow configuration to maximize thermal transfer. It effectively reduces intake manifold temperatures and maintains power consistency under heavy load, providing a claimed gain of +12.4 HP and +4.9 lb-ft of torque.

The intercooler reuses factory mounting hardware and piping, allowing for a straightforward installation process, typically estimated at 1.5 hours for a skilled technician. It is essential to ensure this is installed on the S55 platform; it will not fit subsequent G-series platforms with the S58 engine.

The core construction focuses on durability and thermal performance. By lowering intake temps by approximately -10°F, it helps mitigate heat soak, a common performance limitation during aggressive driving or track sessions.
