Expert technology – what sets Eventuri apart from the competition

The foundation of Eventuri technology is the patented filter housing that leverages the Venturi effect. Air accelerates in a narrowing channel and then maintains laminar flow toward the turbocharger. As a result, the turbo doesn’t have to “fight” to draw in air – it’s supplied more quickly, cooler, and at higher pressure. This translates into more power, better throttle response, and a more linear torque curve.

Unlike standard cone filters, Eventuri isn’t based merely on changing the housing shape. It’s a complete system that includes optimized ducts, multi-layer heat shields, and precision-machined elements, creating a motorsport-grade solution.

Unique design and premium-grade carbon fiber

The Eventuri intake stands out not only for its performance but also for its looks. Every component is handcrafted from prepreg carbon fiber using technology from aviation and motorsport. This makes the components extremely light yet exceptionally strong. The carbon weave gives the engine bay an exclusive character and underscores BMW’s sporty pedigree.

Precise fitment of all components makes installation simple and requires no modifications. The system is fully compatible with BMW’s factory mounting points and air ducts, ensuring perfect fitment for M140i, M240i, and M340i models.

Who is this intake for?

If you’re looking for a solution that:

• delivers real increases in power and torque,
• improves engine throttle response,

– the Eventuri Intake BMW B58 M140i M240i M340i Black Carbon is for you.

Eventuri technology – how the B58 intake works

The Eventuri Intake BMW B58 M140i M240i M340i Black Carbon system is designed around patented technology using the Venturi effect. Unlike classic cone filters that draw air chaotically, Eventuri creates a uniform, laminar airflow at increased velocity. This means the turbocharger receives a greater volume of cooler air, which translates into real power gains and better engine response.

Thanks to the specially shaped filter housing and precisely engineered ducts, Eventuri gains an edge over the competition. The inner surface of the housing is optimized to eliminate turbulence and drag. As a result, air is delivered to the turbocharger faster and more efficiently than with the stock intake system.

Construction of the Eventuri B58 intake kit

Every component of the system has been designed for maximum performance and manufacturing precision. The kit includes:

• Carbon fiber filter housing – lightweight, rigid, and aerodynamically optimized.
• CNC-machined MAF tube – guarantees accurate airflow readings.
• High-flow air filter with a dual-cone design – increases filtration surface area.
• Aluminum air guide – directs air evenly into the filter.
• Heat shields – dual-layer, made of materials resistant to high temperatures.
• Carbon fiber intake ducts – ensure maximum access to cool ambient air.
• Laser-cut brackets – guarantee perfect fitment and stable installation.

Intake housing assembly

The Eventuri filter housing is made entirely from lightweight and durable carbon fiber. Its shape is optimized to guide air smoothly to the turbocharger. The narrowing section creates the Venturi effect, which increases airflow velocity while eliminating swirl and drag. Thanks to this, the B58 engine “breathes” more freely and the turbocharger works more efficiently.

The comparison above shows the difference between the patented Eventuri housing and a classic cone air filter. The Eventuri system wins thanks to its sealed construction and optimized airflow.

Heat shield – the key to low intake temperatures

One of the greatest advantages of the Eventuri Intake is its advanced thermal insulation system. The filter housing is combined with a dual-layer heat shield that protects the intake from heat coming from the exhaust manifold. This solution keeps the intake air temperature as low as possible, improving mixture density and combustion efficiency. As a result, the engine generates more power, and throttle response is instantaneous.

Carbon fiber intake ducts

Eventuri intake ducts are designed to make maximum use of the factory air inlets in the bumper. Positioned just behind the grille, they capture the maximum amount of air and channel it along a smooth curve directly to the filter. Unlike stock ducts, which often have sharp edges that cause turbulence, Eventuri’s design ensures laminar, fast flow, increasing turbocharger efficiency.

Main heat shield – advanced insulation

The Eventuri intake sits right next to the hot exhaust manifold, so a main heat shield is a key element of the design. Its dual-layer construction consists of a silver layer on the exhaust side that reflects radiant heat, and a black layer on the intake side that absorbs residual heat. Between the layers is an air gap acting as an insulator. Tests have shown that the surface temperature of the shield is up to 90°C lower compared with factory solutions.

Secondary heat shield – additional protection

The final element of the insulation system is the secondary heat shield located above the exhaust manifold. Its task is to protect the turbocharger inlet from overheating. Like the main shield, it uses dual-layer technology, which helps maintain low intake air temperatures even in extreme conditions.

Eventuri B58 intake performance tests

The Eventuri Intake BMW B58 M140i M240i M340i Black Carbon system has been thoroughly tested both on a dynamometer and in real driving conditions. The results clearly confirm Eventuri’s advantage over BMW’s stock intake system.

On the dyno, in a BMW M240i with the B58 engine, real power gains of +12–15 HP and torque of +14–18 Nm were achieved. What’s more, the improvement is noticeable across the entire rev range – from low to high – resulting in more linear acceleration and faster throttle response.

It’s worth emphasizing that on a dyno the Eventuri intake relies on a fan blowing air toward the filter. In real-world driving, where airflow is naturally much greater, the effects are even more noticeable. This means that actual on-road gains can be higher than those measured on the test stand.

Comparison with the stock BMW B58 intake

The factory intake system in BMW M140i, M240i, and M340i models is designed as a compromise between performance, noise, and emissions. In practice, this means restricted airflow that limits the full potential of the B58 unit.

Eventuri introduces fundamental changes:

• Greater airflow: the patented housing and dual intake ducts provide maximum supply of cool air to the turbocharger.
• Lower intake temperatures (IAT): thanks to Eventuri’s multi-layer heat shields, the air retains its density.
• Laminar flow: eliminating turbulence improves turbocharger operation and overall system dynamics.
• Premium sound: under acceleration the engine produces a deeper, sportier tone while maintaining acoustic comfort at steady speeds.

In practice, the difference is noticeable from the first press of the accelerator. The car becomes more responsive and the turbo spools faster – something especially appreciated by drivers who enjoy dynamic driving.
