Eventuri BMW G29 Z4 2.0 B48 Carbon Intake

In the Z4, 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 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.
