The M177 Polymer Carbon Fiber High Flow Intake is a game-changer for intake technology on the C63 and GLC63 platforms. Our tube design utilizes a fully flow-optimized channel with optimal filter placement for direct cold air injection into the filter. Our oval design opening is equivalent to a 4.5" circular diameter, which is the largest on the market. Constructed from a polyamide and carbon fiber blend to yield excellent thermal performance and prevent heat soak.

This patent-pending product has exhibited 63whp gains (75 crank hp gain) above the stock intake with stage 2 (stock turbo, stock fuel system) calibrations. With upgraded turbos and fueling, this design set the fastest 60-130mph record at 4.9s for a W205 C63. (These results will vary based on the tuner and supporting mods.)

Consult your tuner before purchasing to ensure they calibrate the air box sensor to account for increased airflow.
