The intake system of the Mercedes GLC63S AMG is the result of extensive development and testing. Our design brief consisted of 3 main objectives: 1) Increased flow rate. 2) Low intake temperatures. 3) Smooth airflow. The first objective was achieved by utilizing all the limited available space in the engine bay of the GLC63S, resulting in a 39% higher flow rate compared to the standard system. The second objective was achieved by designing a fully sealed system. The engine bay of the GLC63S reaches high temperatures with heat sources such as the turbos in close proximity to the intake, so it is crucial that the intake remains sealed. The final goal was achieved by designing an organically shaped system with specially rounded plate filters to ensure the airflow path contains no sharp corners and therefore allows laminar flow.

When all three goals are achieved, our W205 C63S intake system delivers on all fronts and allows the turbos to generate boost more efficiently. This results in improved throttle response and real power gains that increase with higher tuning states.

Dyno tests were performed on both a full C63S and a stage 2 C63S with downpipes and a remapping. Below is the dyno chart for the stage 2 car, which had the same tune on all runs and only the airbox was changed. It is important to note that the hood was closed for all runs to simulate road conditions. Dyno tests with the hood open - especially with open cone intakes do not give a reliable indication of how the intakes affect performance. On the road, the hood is closed and so all the heat from the turbos is trapped in the engine bay. On the C63S, this is intense heat, which is why a closed system is so important. Dyno testing a system with the cone open and the hood open brings benefits, but once on the road the heat soak will significantly affect performance as the open cones draw in the hot air. At higher air temperatures, the density is lower, the turbos don't make as much thrust, resulting in lower power. Once the car accelerates and the open cone inlets are drawn through the existing stagnant hot air, they continue to draw in the heat generated by the engine and turbos as they spool. When the engine is under load and accelerating, turbos generate a lot of heat, which can even be seen on the red glowing hot sides.

It can be seen here with our fully sealed system that power increases linearly after 4800 rpm where the airflow requirement increases and the stock airboxes become a restriction. These power gains were measured after only the stock airbox was modified for the Eventuri intake all other modifications were present for both the stock airbox and the Eventuri intake.

The gains measured on the dyno result in increased part throttle and full throttle response on the road, with the car pulling much more eagerly to the redline. The tests were conducted back-to-back on the same day and temperatures were monitored to ensure consistency. The car was initially tested with the hood closed. We then left the car on the dyno and fitted the Eventuri. The car was then driven again - hood closed. Several runs were made with both configurations to get a consistent result.

The intake system of the Eventuri GLC63S AMG consists of a series of components designed for a specific purpose and manufactured to the highest standards. Here are the details for each component and the design ethos behind them:

Each intake system consists of:
2 x carbon fiber airbox lids with turbo inlet transitions
2 x carbon fiber airbox bases with inlet duct transitions
2 x bespoke high flow panel filters
2 x CNC machined stainless steel inlet flanges
4 x CNC machined aluminum filter flanges
2 x CNC machined MAP bosses
4 x CNC machined rubber brackets
Laser cut stainless steel brackets
