BMW G20 G21 318i 320i 330i 330e B48 Eventuri carbon air intake

Mounting for the G20 318i 320i 330i 330e

 

The BMW G20 B48 Eventuri intake has been developed to give the turbocharger a less restrictive flow path while maintaining low intake temperatures. Heat and volume are the most important considerations when designing an intake for turbocharged engines.

In the G20, the intake system is located next to the exhaust manifold, which quickly warms up the engine bay. High temperatures are detrimental to engine performance as the turbo would have to build boost using heated, less dense air, so the only way to ensure IATs are kept to a minimum is to have a fully sealed intake. However, this results in a limitation with only one supply of air from which to draw air. During development, we noticed an additional gap in the wheel arch and took advantage of this by adding a secondary feed to our airbox. Additionally, our sealed airbox also features a gold reflective heat shield to minimise radiant heat transfer from the exhaust manifold.

To maximize volume we made the airbox as large as possible with a cutout for any strut mounts. The standard convoluted inlet pipe has been replaced with a smooth carbon pipe that is also larger in internal volume with a starting internal diameter of 111mm (4.4″) gradually tapering towards the turbo inlet. The pipe ensures 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 surface area than the standard filter.
