GruppeM Mercedes-Benz C63 AMG W205 4.0L FRI-0407

Upgrade the intake system of your Mercedes-Benz C63 AMG / C63 S W205 4.0L Twin-Turbo with the GruppeM Ram Air System FRI-0407, developed to improve fresh-air delivery, manage intake temperatures and enhance the performance character of the AMG V8.

The system features a dedicated carbon-fiber filter casing and intake ducting designed around the W205 engine bay. The carbon enclosure helps prevent hot air from entering the intake stream, while the fresh-air path directs cooler ambient air toward the filters. GruppeM states that the system lowers and stabilizes intake air temperatures while improving torque and power throughout the rev range.

A key feature of the FRI-0407 is its oversized air guide, specified at approximately 160% larger than the factory guide. The larger intake opening is designed to streamline the incoming airflow and increase the supply of fresh air to the 4.0L Twin-Turbo V8.

The system also enhances the Induction Sound, giving the M177 V8 a stronger and more engaging intake character during acceleration. The combination of carbon construction, improved airflow and heat isolation creates a performance-focused intake solution while adding a distinctive motorsport-inspired appearance to the engine bay.

The FRI-0407 is officially listed for the Mercedes-Benz C-Class W205 C63 AMG 4.0L Twin-Turbo, with vehicle types including 205086 / 205286 / 205386, as well as C63 S AMG models 205087 / 205287 / 205387 / 205487. The application uses the M177 engine and covers the W205 platform from 2015 onward.

The system is designed for bolt-on installation using a dedicated fitting adapter, with two replacement filters specified as K&N 33-3072 according to the GruppeM application data.

The GruppeM FRI-0407 Ram Air System is an ideal upgrade for C63 and C63 S W205 owners looking to enhance Intake Airflow, Intake Temperature Management, Induction Sound and Engine Response with a dedicated carbon intake system.
