Eventuri carbon cold air intake BMW G20 G21 B58

Mounting for the G20 G21 M340i

The BMW G20 G21 B58 Eventuri intake has been developed to give the turbo a less restrictive flow path while keeping intake temperatures low. Heat and volume are the most important considerations when designing an intake for turbo engines. In the G20 G21, the intake system is located next to the exhaust manifold, which quickly warms the engine compartment. High temperatures are detrimental to engine performance because the turbo would have to build boost with heated, less dense air and so the only way to ensure IATs are kept to a minimum is a fully sealed intake. However, this results in a limitation with only one supply of air supply from which air can be drawn. During development we noticed an additional gap in the wheel arch and took advantage of this by adding a secondary power supply to our airbox. Additionally, our sealed airbox also features a gold reflective heat shield to minimize radiant heat transfer from the exhaust manifold. To maximize volume, we made the airbox as large as possible with a recess for any strut brackets. The stock convoluted intake pipe has been replaced with a smooth carbon pipe that is also larger in internal volume with a starting inside diameter of 111mm (4.4″) that gradually tapers towards 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 filter area than the standard filter.
