Eventuri Carbon intake system suitable for BMW G2x G42 B48 B58 incl. M240i M340i(x)

Eventuri carbon intake system for BMW 3 Series/4 Series G20 G21 G22 G42 B48/B58 incl. M240i|M340i(x)

DANGER: EXPERT REPORT ONLY APPLIES TO THE B58 VARIANTS!!

The variant for cars B58 built AFTER November 2018 also fits on the G42 M240i.

Also fits G22 4 Series with B48 engine (420i(x) and 430i(x))

DANGER: All models built before 2018 still have an air mass sensor installed. All models built after 2018 have a temperature sensor. Therefore, there are two different products for both engine variants.

Suitable for the following models:

BMW G2x

B48B20:
– 318i
– 320i(x)
– 330i(x)

B58B30TÜ1:
– M340i(x)

The Eventuri intake system suitable for BMW G20/G21 B48/B58 was designed to provide a less restrictive flow path for the turbo while maintaining low intake temperatures. Heat and volume are key considerations when designing an intake system for turbocharged engines. On the G20, the intake system is located next to the exhaust manifold, which quickly sweeps the engine bay with heat. High temperatures are detrimental to engine performance as the turbo would need to be charged with heated, less dense air, so the only way to keep IATs to a minimum is to have a fully sealed intake. However, this results in a limitation with only one supply air feed to draw air from. During development, we identified an additional opening in the wheel arch area and took advantage of this by adding a second feed to our airbox.

In addition, our sealed airbox also features a gold reflection heat shield to minimize radiant heat transfer from the exhaust manifold. To maximize volume, we made the airbox as large as possible with a cutout for potential strut bracing. The stock corrugated intake pipe has been replaced with a smooth carbon pipe that also has a larger internal volume with an initial internal diameter of 111mm (4.4?) and gently tapers downwards to match the turbo inlet. The pipe 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 filter area than the stock filter.

The G20/G21 B48/B58 Eventuri intake system consists of a number of components designed for a specific purpose and manufactured to the highest standards. We use 100% prepreg carbon fibre with no glass fibre, which means we can achieve a smooth internal surface to get a more consistent airflow. Here are the details for each component and the design ethos behind it:

Each intake system consists of:

carbon airbox with two inlets

Custom-designed high-flow dry cone filter

carbon intake pipe
bracket for CNC-machined temperature sensor

CNC machined vent adapters

heat shield with reflective gold foil

Laser-cut stainless steel brackets
Silicone reducer with clamps according to OEM specifications

If we do not explicitly mention a parts certificate or a general operating permit (ABE) in the product text, it is a motorsport article that is not approved under the Road Traffic Regulations (StVO) and therefore the operating permit expires if no entry is made in accordance with Section 21 StVO!
