Eventuri BMW E9X M3 Carbon Fibre Plenum Eventuri Carbon Fibre Plenum For The BMW E9X M3 — Engineered To Deliver A Rich, Authentic V8 Induction Roar While Retaining OEM Drivability For Your S68 Engine. The Eventuri Carbon Fibre Plenum replaces the factory plastic air chamber with a stunning full-carbon design that redefines the M3’s induction character. Constructed entirely from pre-preg carbon fibre, including the internal trumpets, it maintains the factory internal volume — ensuring perfect drivability and air-fuel ratios while transforming the sound into a deep, resonant V8 growl that builds through the rev range. While the performance gains from the plenum alone are modest, the intake sound transformation is extraordinary — making it one of the most sought-after upgrades for any E9X M3. When combined with the Eventuri Intake and Carbon Ducts, it forms a harmonised induction system that improves response and creates one of the most engaging naturally aspirated soundtracks available. Every plenum is built to exacting tolerances, using CNC-machined flanges and fittings to ensure perfect sealing and OEM-quality fitment. Please note in the pictures you will see additional Eventuri parts installed such as the carbon fibre air intake and air ducts. These can be purchased separately if required.
