The Mercedes W205 C63/S AMG intake system is the culmination of extensive development and testing. Our design consisted of 3 main objectives:
1) Increased flow
2) Low inlet temperatures
3) Smooth airflow
The first objective was achieved by utilising all the limited space in the engine bay of the C63S, resulting in a 35% higher flow rate compared to the original system. The second goal was achieved by developing a fully enclosed system. The C63S engine bay reaches high temperatures with heat sources such as the turbos in close proximity to the intake system, so it is critical that the intake system remains sealed. The end goal was achieved by designing an organically moulded system with individual rounded panel filters to ensure the airflow path contained no sharp corners, keeping the flow laminar. With smooth transitions from the filters to the turbo inlets, our intake system minimises the creation of turbulence, allowing the turbos to operate more efficiently.When all 3 objectives are achieved, our intake system for the W205 C63(S) delivers on all fronts and allows the turbos to generate boost more efficiently. This leads to improved throttle response and real power gains, which increase the more power the engine has.

As there are various turbo upgrades available for the C63/S, we have also developed a special solution for larger turbos.
Our C63/S intake is available in 2 configurations:
61 mm ID outlets to fit standard turbos and 76.5 mm ID outlets to fit larger turbos.

Power increase: Stage 2 C63S: 22-30hp, 20-24ft-lb
Power increase: Original C63S: 10-12hp, 12-15ft-lb

Dyno tests were performed on both a full C63S and a Stage 2 C63S with downpipes and software optimisation. Below is the dyno chart for the Stage 2 car that had the same tune for all runs and only the airbox was changed. It is important to note that the bonnet was closed for all runs to simulate road conditions. Dyno tests with the bonnet open - especially with open conical intakes - do not give a reliable indication of how the intake system affects performance. On the road, the bonnet is closed and so all the heat from the turbos is retained in the engine bay. On the C63S, this intense heat is a problem, which is why a closed system is so important. As the higher air temperature is less dense, the turbos don't make as much pressure, resulting in lower power.Here, our fully sealed system shows that power increases linearly after 4800 rpm, where the airflow requirement increases and the original airboxes become a restriction. These power gains were measured after only the original airbox was swapped for the Eventuri intake system - all other changes were present for both the original airbox and the Eventuri intake system.The gains measured on the dyno translate to increased part-throttle and full-throttle response on the road, with the car pulling much more eagerly to redline. Testing was conducted back-to-back on the same day and temperatures were monitored to ensure consistency. The car was first tested with the bonnet closed. We then left the car on the dyno and installed the Eventuri. The car was then driven again - bonnet closed. Several runs were carried out with both configurations to achieve a consistent result.
