GruppeM Subaru Impreza GDA GDB 2.0L Ram Air FR-0407

Upgrade the intake system of your Subaru Impreza GDA/GDB 2.0L Turbo with the GruppeM Ram Air System FR-0407, developed to improve fresh-air delivery, manage intake temperatures and enhance the performance character of the turbocharged boxer engine.

The system features a dedicated carbon-fiber air duct and filter casing designed to separate the intake path from hot air inside the engine bay. The duct helps direct a greater supply of fresh ambient air toward the filter, supporting more stable intake temperatures during performance driving.

A large-format air guide helps streamline the incoming airflow into the intake system, improving the efficiency of the air supply to the turbocharged engine. The design is intended to provide a more direct and consistent flow of fresh air compared with the factory arrangement.

The carbon-fiber construction adds a premium motorsport-inspired appearance to the engine bay while also enhancing the Induction Sound of the boxer turbo engine. The combination of optimized airflow and fresh-air delivery helps support sharper throttle response and a more engaging Driving Experience.

The GruppeM FR-0407 is designed for the Subaru Impreza GDA/GDB platform from 2005–2007, with the official application covering the EJ20(T) Late 2.0L Turbo specification. Overseas 2.5L applications are also listed separately as compatible, so the exact engine specification should be confirmed before ordering.

The system is designed around a vehicle-specific bolt-on installation and includes the dedicated components required for the FR-0407 application.

The GruppeM FR-0407 Ram Air System is an ideal upgrade for Subaru Impreza owners seeking improved Intake Airflow, Intake Temperature Management, Induction Sound and Engine Response from the 2.0L Turbo platform.
