EVENTURI Air Intake System For Mercedes-Benz CLA45 CLA45s AMG C118 With M139 Engine.
Performance Increase : 15-18hp, 12-16ft-lb
The Mercedes M139 intake for the CLA45 and CLA45s has been developed to allow the turbo a smoother route for airflow to be drawn from. By redesigning the system to allow for a much more direct path, the turbo is able to generate boost with less drag and therefore reach target boost pressure sooner in the RPM range. This intake system has been developed to offer the highest possible flow rate whilst maintaining the lowest intake temperatures possible to produce a net performance gain. The de-restricted flow path also allows for turbo spool to be heard more clearly adding to the dynamics of the overall driving experience.
The Eventuri Difference
The Mercedes M139 Eventuri system uses our Patented Carbon fiber Housing which provides an aerodynamically efficient airflow path from the filter to the turbo. Not just another cone filter with a heat shield but a unique design which invokes the Venturi affect and maintains laminar flow conditions to reduce the drag on the turbo.
The Eventuri CLA45/CLA45s intake system consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standards. We use 100% pre-preg carbon fiber with no fibreglass which means we can achieve a smooth internal surface to maintain smoother airflow. Here are the details for each component and the design ethos behind them:
Each intake system consists of:
Patented Venturi Filter Housing Assembly
The M139 filter housing comprises of a bespoke high flow filter, aluminium cowl and the carbon pod itself. The carbon pod shrouds the reverse mounted filter and smoothly shape the airflow down to the intake tubes. This smooth reduction in cross sectional area invokes the Venturi effect where the airflow accelerates whilst maintaining laminar conditions. It can be thought of as a large velocity stack - below is a diagram to show the comparison between our patented design and a regular intake system.
Carbon Fiber Intake Duct
The duct channels ambient air from the slam panel area to the filter housing. It fits inside the OEM ducting system and smoothly transitions to the circular filter housing shape. In order to ensure a good seal against engine bay heat - it also has a flexible rubber edging around the opening which presses against the filter housings creating the desired seal yet allowing the housing to move with the engine. The side of the duct has some cut outs which allow air movement around where the ECU is now relocated to aid with heat saturation. The duct was designed to have the maximum internal volume possible within the given geometry of the engine bay. This ensures that the filter housing is able to draw with minimum restriction.
Laser Cut ECU Relocation Bracket
In order to relocate the ECU we have designed a bracket which is laser cut from stainless steel for strength and rigidity. The ECU securely mounts into this bracket which is then secured to the chassis of the car using the stock locating threads used for the OEM airbox bracket. In addition, there is another bracket which supports the filter housing and finally a piece which covers the top of the ECU to protect the wiring harnesses.

Eventuri was founded by a team of engineers and enthusiasts with a background in Aeronautics and tuning – all sharing a passion for cars and performance. After owning various intakes over many years for our own cars and being disappointed with the gains which seldom lived up to their claims – we decided to take things into our own hands and rewrite the book. Eventuri set a new benchmark in intake design and technology, above all – to engineer systems which provide real gains and then to publish genuine figures.
Eventuri intake systems are extensively developed using cutting edge design, testing and prototyping methods. With a focus on performance, each design undergoes CFD analysis and is then validated at the prototype stage through volumetric airflow, intake temperature and extensive dynamometer testing. Eventuri strive to publish all the development information to illustrate the depths we go to in bringing an intake from concept to reality.
Only the best materials are selected for each component – even down to the choice of fasteners and fixings in order to ensure that the quality of the end product is second to none.
