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 testsThe 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:

The Mercedes A35 Eventuri turbo pipe was developed to offer the turbo a less restrictive flow path compared to the standard pipe. We have succeeded in increasing the internal volume and eliminating the corrugated, flexible section on the airbox side. By using a completely solid pipe all the way from the intake tract to the turbo, the flow path is smoother and the airflow can remain more laminar. To accommodate the movement of the engine, our A35 intake has a "floating" pipe that can move within the airbox. The shape of the carbon tube on the turbo side has been optimised using CFD to minimise turbulence. The connection to the turbo is achieved by an innovative silicone coupling, which has an internal thermal separator between the carbon pipe and the metal turbo housing. The multiple vent ports at the rear of the pipe are done with a CNC machined block that also provides a smooth internal surface for airflow within the pipe.
The Eventuri A35-A250 turbo inlet pipe is made from prepreg carbon fibre and comes with a range of other components designed for a specific purpose and manufactured to the highest standards.
It is available to fit the A35, CLA35 and A250. The inlet pipe is only suitable for our intake system.
Each intake system consists of:
Prepreg carbon pipe
CNC-milled breather block
CNC-milled MAP boss
CNC-milled breather nozzle
CNC-milled reinforcement ring
Laser-cut bracket
Silicone couplings with oil-resistant lining
Marine grade stainless steel hose clamps
