Reducing heat pull and increasing internal volume are the main considerations when designing an intake system for turbocharged engines. On the A35, the intake system is located in close proximity to the exhaust manifold, which heats up the engine bay quickly. High temperatures are detrimental to engine performance as the turbo must build boost with heated, less dense air, so the only way to keep IAT to a minimum is with a fully sealed intake tract. To reduce the restrictions of a closed intake 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 intake pipe has a larger internal volume with an initial internal diameter of 111mm (4.4?) which gently tapers to match the turbo intake pipe diameter. Finally, we use a custom made high flow dry filter which is ISO approved and has a larger filtering area than the stock filter.Dyno testingThe dyno testing was carried out by MSL Performance, a Mercedes specialist based in the UK. A completely stock A35 AMG was tested with the stock airbox and then with the Eventuri intake system, with external conditions being the same. As can be seen below, the intake offers a power gain across the entire rev range. The highlighted point shows a significant power gain as the intake tract allows a higher flow rate in the higher rpm range where the stock airbox becomes a restriction. The resulting power 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 turbo's demand increases.The Eventuri A35 intake system consists of a series of components designed for a specific purpose and manufactured to the highest standards. We use 100% pre-impregnated carbon fibre with no fibreglass, meaning we can achieve a smooth internal surface to maintain a more consistent airflow.
