EVENTURI CARBON INTAKE KIT BMW M240i G42 B58

Description

The G42 B58 Eventuri intake was developed to provide the turbo with a less restrictive flow path while maintaining low inlet temperatures. Heat and volume are the main considerations when designing an intake for turbo engines. In the M240i, the intake system is located next to the exhaust manifold which quickly absorbs heat from the engine compartment.
High temperatures are detrimental to engine performance as the turbo is expected to increase boost with heated, less dense air and so the only way to ensure IATs are minimized is with a fully sealed intake. This, however, results in a restriction with only one spare air supply to draw air from. During development we noticed an additional opening in the wheel arch area and took advantage of this by adding a secondary power supply to our airbox.
Additionally, our sealed airbox also has a gold-tinged heat shield to minimize radiative heat transfer from the exhaust manifold. To maximize volume we made the airbox as large as possible with a recess for potential strut reinforcements. The stock twisted intake tube is replaced with a smooth carbon tube that is also larger in internal volume with a starting internal diameter of 111mm (4.4"") that tapers smoothly to fit the turbo inlet. The tube provides a smooth path from the filter to the turbo inlet. Finally we use a custom high-flow dry filter that is ISO tested for filtration performance and has a larger filtration area than the stock filter.

The Eventuri G42 B58 intake system consists of a series of components designed to perform a specific purpose and manufactured to the highest standards. We use 100% pre-preg carbon fiber without glass fiber, which means we can achieve a smooth internal surface to maintain smoother airflow. Below are the details for each component and the underlying design ethics.

Each suction system consists of:

Carbon fiber airbox with dual fuel supply

Custom-made high flow dry cone filter

Carbon fiber inlet tube with internal diameter of 111 mm

CNC machined temperature sensor holder

CNC machined vent adapter

Heat shield with golden reflective back

Laser cut stainless steel brackets

CNC machined turbo flange and custom silicone
