Eventuri carbon intake for Mercedes Benz A35 AMG W177

Description

Performance increase: 15-20 hp, 20,40 Nm to 24,40 Nm

The Mercedes A35 AMG Eventuri intake was developed to provide the turbo with a less restrictive flow path while maintaining low intake temperatures. Reducing heat absorption and increasing internal volume are key considerations when designing an intake for turbocharged engines. In the A35, the intake system is in close proximity to the exhaust manifold which quickly absorbs heat from the engine bay. High temperatures are detrimental to engine performance as the turbo would have to generate boost with heated, less dense air. The only way to ensure that IATs are kept to a minimum is therefore to have a fully sealed intake. In order to reduce the restriction of a sealed intake, we increased the volume of the airbox by relocating the ECU and also allowing an opening into the airbox on the cold side, away from the direct heat of the manifold. The carbon intake tube has a larger internal volume with a starting internal diameter of 111mm (4,4″) that gradually tapers to match the turbo inlet pipe. Finally, we use a custom-made high-flow dry filter, ISO tested for filtration performance and featuring a larger filtration surface area than the stock filter.
