Suitable for G01 X3 M40i and G02 X4 M40i, engine variant B58D
The aspiration The BMW X3 M40i's Eventuri has been developed to provide the turbo with a less restrictive flow path, keeping inlet temperatures low.
In the M40i, the closeness of the intake system to the exhaust manifold presents a challenge , rapidly heating the engine compartment. High temperatures compromise engine performance, making a solution that ensures minimum intake air temperatures (IAT) necessary. Our solution includes a fully sealed intake system, designed to counteract heat absorption and prevent the turbo from sucking in hot air.

High temperatures compromise engine performance, making a solution that ensures minimum intake air temperatures (IAT) necessary. Our solution includes a fully sealed intake system, designed to counteract heat absorption and prevent the turbo from sucking in hot air.
Additionally, our sealed airbox features a heat shield coated in gold reflective material, which minimizes radiative heat transfer from the exhaust manifold. To optimize airflow volume, we've maximized the size of the airbox, incorporating a recess to seamlessly accommodate the strut brace.
Replacing the stock convoluted intake tube, our design employs a pre-preg carbon tube, which boasts a much larger internal volume with a 109mm (4.3") internal diameter that tapers seamlessly to match the turbo inlet, ensuring an uninterrupted airflow path. Completing this design is a custom high-flow dry filter, rigorously tested for ISO-certified filtration performance and boasting a larger filtration area than the stock filter. series.
The Eventuri X3/X4 M40i intake system is made up of a series of components designed to perform a specific purpose and manufactured to the highest standards. We use 100% pre-preg carbon fibre with no fibreglass, which means we can achieve a smooth internal surface to maintain a smoother airflow. Here are the details for each component and the design ethos behind them:
Each intake system consists of:
Fiber airbox carbon
Made in pre-preg carbon fiber, the airbox effectively seals the filter from the heat of the engine bay. As the airbox is positioned next to the exhaust manifold, it is essential that the filter is completely sealed, so we designed the airbox to encapsulate the filter while providing a large internal volume. To seal the intake pipe we designed a laser cut plate with a rubber sealing strip that attaches to the airbox. The intake pipe passes through the plate and the rubber seal ensures that hot air does not enter the airbox. To further reduce heat absorption, there is an additional heat shield with a gold reflective layer on the side of the exhaust manifold that effectively combats radiant heat transfer.
Carbon inlet pipe
The stock inlet pipe has a flexible, twisted section to provide movement with the engine. This however also adds the possibility of turbulence in the flow path as there are more faces which can cause vortices. We replace this with our carbon pipe which is smooth and also has a higher internal volume. Unlike most aftermarket intakes, we have maximized the size of our intake tube, the OEM inlet tube has an internal diameter of 80.8mm or 3.2" at the filter end. Our tube has an internal diameter of 109mm or 4.3". This equates to a whopping 82% increase in cross-sectional area over stock. The tube tapers gently towards the stock turbo inlet to ensure airflow remains as laminar as possible. The tube also has a CNC machined fitting for the temperature sensor and vent adapter.
Custom Cone Filter
Our cone filter is made from a double layer non-woven mesh material and is ISO tested to ensure filtration is in in line with OEM standards. The filter is cleanable and very stable at high temperatures with the urethane base material. The filter incorporates an internal flow guide cone to help the airflow converge while reducing the possibility of a stagnation point in the center of the filter space. The filter media has significantly more surface volume than the stock panel filter.
