GruppeM Subaru Impreza GDA GDB 2.5L Ram Air System

Upgrade the intake system of your Subaru Impreza GDA/GDB 2.5L Turbo with the GruppeM Ram Air System FR-0407, designed for overseas-specification models to improve fresh-air delivery, manage intake temperatures and enhance the engine's performance character.

The system uses a dedicated carbon-fiber air duct and filter casing to help isolate the intake from hot air within the engine bay. The duct is designed to direct a greater supply of fresh ambient air toward the filter, supporting more consistent intake air temperatures during spirited driving.

A large-format air guide helps streamline the incoming airflow into the intake system. This design is intended to improve the efficiency of the air supply to the turbocharged engine while also giving the intake system a more purposeful performance-oriented character.

The carbon-fiber construction provides a premium motorsport-inspired appearance and helps enhance the Induction Sound of the turbocharged boxer engine under acceleration. The combination of improved airflow and a more direct fresh-air supply is designed to support sharper engine response and a stronger overall driving feel.

The GruppeM FR-0407 is designed around the Subaru Impreza GDA/GDB platform from 2005–2007 and is compatible with the corresponding overseas 2.5L Turbo specification. Fitment should be confirmed against the vehicle's exact specification before ordering.

Installation is designed around a vehicle-specific bolt-on configuration, with the necessary intake components and heat-management hardware supplied according to the FR-0407 application.

The GruppeM FR-0407 Ram Air System is an ideal upgrade for Subaru enthusiasts seeking improved Intake Airflow, Intake Temperature Management, Induction Sound and Engine Response from the 2.5L Turbo platform.
