ATTENTION: All models built before 2018 still have a mass air flow sensor installed. All models built after 2018 have a temperature sensor. There are therefore two different products for both engine variants.

The BMW G20/G21 B58 Eventuri intake system was developed to provide the turbo with a less restrictive flow path while maintaining low intake temperatures. When designing an intake system for turbocharged engines, the focus is on heat and volume. On the G20, the intake system is located next to the exhaust manifold, which quickly infuses the engine bay with heat. 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 keep IATs to a minimum is to have a fully sealed intake. However, this leads to a restriction with only one supply air intake from which air is drawn. During development, we identified an additional opening in the wheel arch area and took advantage of 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've made the airbox as large as possible with a cutout for potential strut bracing. The standard corrugated intake pipe has been replaced with a smooth carbon pipe, which also has a larger internal volume with an initial internal diameter of 111 mm (4.4") and tapers gently 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 standard filter.

The G20/G21 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 fiber with no fiberglass, which means we can achieve a smooth inner surface to get a smoother airflow. Here are the details for each component and the design ethos behind them:

Each intake system consists of:
Carbon airbox with two inlets
Customized high-flow dry-cone filter
Carbon intake tube
Bracket for CNC-milled temperature sensor
CNC-milled vent adapter
Heat shield with reflective gold foil
Laser-cut stainless steel brackets
Silicone reducer with clamps to OEM specification
