The Eventuri B58 CARBON INTAKE SYSTEM for the BMW B58 G20 G21 M340I(X) is an essential item for any mod list.
The BMW G20 B58 Eventuri intake has been developed to provide the turbo with a less restrictive flow path whilst maintaining low inlet temperatures. Heat and Volume are the main considerations when designing an intake for turbocharged engines.
In the G20, the intake system is located next to the exhaust manifold which rapidly heat soaks the engine bay. High temperatures are detrimental for engine performance as the turbo would have to build boost with heated, less dense air and so the only way to ensure IAT’s are kept to a minimum is for a fully sealed intake. This, however, results in a restriction with only one stock air feed to draw air in from.
During development, Eventuri noticed an additional opening into the wheel arch area and took advantage of this by adding a secondary feed to the airbox. Furthermore, our sealed airbox also has a heat shield with gold reflective to minimise the radiative heat transfer from the exhaust manifold. In order to maximise volume, we made the airbox as large as possible with a recess for potential strut braces. The stock convoluted intake tube is replaced with a smooth carbon tube which is also larger in internal volume with a starting internal diameter of 111mm (4.4″) smoothly tapering down to match the turbo inlet. The tube provides a smooth path from the filter to the turbo inlet. Finally, we use a custom made high-flow dry filter that is ISO tested for filtration performance and has a larger filtration area than the stock filter.
