The BMW G42 B48 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 G42 2-Series, the intake system is located next to the exhaust manifold which rapidly heat soaks the engine bay. High temperatures are detrimental to engine performance as 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 for a fully sealed intake. This, however, results in a restriction with only one stock air feed to draw air in from. During development, we noticed an additional opening into the wheel arch area and took advantage of this by adding a secondary feed to our airbox. Furthermore, our sealed airbox also has a heat shield with gold reflective to minimize the radiative heat transfer from the exhaust manifold. In order to maximize 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 which is ISO tested for filtration performance and has a larger filtration area than the stock filter.
The Eventuri Difference
The G42 B48 Eventuri system uses our Patented Carbon Fiber Housings with our Gen 2 bespoke filters, which provide an aerodynamically efficient airflow path from the filter to the turbos. Not just another cone filter with a heat shield but a unique design that invokes the Venturi effect and maintains laminar flow conditions to reduce the drag on the turbo.
