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

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

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

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

ATTENTION: 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.

Pay attention:

The BMW G20/G21 B48/B58 Eventuri intake system was developed to provide the turbo with a less restrictive flow path while maintaining low intake temperatures. Heat and volume are paramount when designing an intake system for turbocharged engines. On the G20, the intake system is located next to the exhaust manifold, which quickly draws heat through the engine bay. High temperatures have a detrimental effect on engine performance, as the turbo would have to be charged with heated, less dense air, so the only way to minimize IATs is with a fully sealed intake. However, this results in a limitation with only a single supply air intake from which air is drawn. During development, we identified an additional opening in the wheel arch area and exploited this by adding a second intake to our airbox.

In addition, our sealed airbox also features a gold-reflective heat shield to minimize radiant heat transfer from the exhaust manifold. To maximize volume, we cut out the airbox as much as possible to accommodate potential strut bracing. The stock corrugated intake pipe was replaced with a smooth carbon tube that also has a larger internal volume, with an initial internal diameter of 111 mm (4.4 in) 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-made high-flow dry air filter that is ISO-approved for its filtration performance and has a larger filter surface than the stock filter.

The G20/G21 B48/B58 Eventuri intake system consists of a series of components designed for a specific purpose and manufactured to the highest standards. We use 100% prepreg carbon fiber with no fiberglass, which allows us to achieve a smooth internal surface for 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-made 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
