Eventuri BMW G29 Z4 M40i B58 Black Carbon Intake System

OVERVIEW

The Eventuri Black Carbon Intake System for the BMW G29 Z4 M40i replaces the restrictive factory airbox and convoluted inlet tract with a fully sealed prepreg carbon airbox and a smooth carbon fiber inlet tube. Cross-sectional area of the intake tube increases 82% over stock (109mm vs 80.8mm OEM), while dual cold-air feeds — one from the front and one from the wheel arch — draw cooler, denser air away from the exhaust manifold. The sealed housing and gold-backed heat shield minimize heat soak in the Z4's tightly packaged engine bay. Built from 100% prepreg carbon fiber with no fibreglass. Designed and hand-assembled in the UK.
