The Mercedes A35 AMG Eventuri intake system was developed to provide the turbo with a less restrictive flow path while keeping intake temperatures low. Reducing heat suction and increasing internal volume are the main considerations when developing an intake system for turbocharged engines. In the A35, the intake system is located in close proximity to the exhaust manifold, which quickly heats up the engine compartment. High temperatures have a detrimental effect on engine performance, as the turbo has to build up boost pressure with heated, less dense air. Therefore, the only way to reduce IAT to a minimum is to have a completely sealed intake tract. To reduce the restrictions of a closed intake tract, we increased the volume of the airbox by relocating the ECU and providing an opening in the airbox on the cold side, away from the direct heat of the manifold. The carbon inlet pipe has a larger internal volume with an initial internal diameter of 111mm (4.4?) which tapers smoothly to match the turbo inlet pipe diameter. Finally, we use a custom high-flow dry filter that is ISO approved and has a larger filter area than the stock filter.

Dyno tests
The dyno tests were carried out by MSL Performance, a Mercedes specialist based in the UK. A fully standard A35 AMG was tested with the standard airbox and then with the Eventuri intake system, with the same external conditions. As can be seen below, the intake system offers an increase in power throughout the rev range. The highlighted point shows a significant power gain as the intake allows a higher flow rate in the higher rev range where the stock airbox becomes a restriction. The resulting performance gains are noticeable on the road, with better throttle response and improved acceleration times. With a tuned A35 we would expect even better gains as the demand from the turbo increases.

The Eventuri A35 intake system consists of a number of components designed for a specific purpose and manufactured to the highest standards. We use 100% pre-impregnated carbon fiber without fiberglass, which means we can achieve a smooth inner surface to get a smoother airflow. Here are the details for each component and the design ethos behind them:

Each intake system consists of:
Carbon airbox
Custom high-flow dry-cone filter
Carbon intake tube
CNC-machined intake flange
Laser-cut stainless steel brackets and ECU cover
Silicone coupler with OEM clamps
