Introducing the Eventuri S85 Carbon Fiber Plenum – a true centerpiece for BMW’s iconic V10 engine. Crafted entirely from 100% premium prepreg carbon fiber, right down to the internal trumpets, this masterpiece is a direct replacement for the factory plastic plenum. Every curve, contour, and component has been meticulously engineered with one clear purpose: to transform the emotional character of the S85 while preserving its pure performance DNA.

While this carbon plenum doesn’t aim to increase power figures, it amplifies the driving experience in a way that numbers can’t express. By retaining BMW’s original internal volume and trumpet geometry, the plenum maintains the S85’s signature power delivery and torque curve — yet unleashes an intoxicating induction symphony that brings every rev to life. The result is a deeper, sharper, and more mechanical tone that turns each throttle input into an event.

Compatible with OEM airboxes and most aftermarket intake systems, the Eventuri S85 Carbon Plenum is designed for seamless integration and long-term reliability.

Each Plenum Features:

• 100% Prepreg Carbon Fiber Construction – including both base and lid

• 10 Carbon Fiber Velocity Trumpets – precisely matched to OEM specifications

• 10 CNC-Machined Aluminum Flanges – ensuring perfect alignment and durability

• CNC-Machined Breather Bosses – for precise, leak-free integration

Engineering Meets Emotion

The Eventuri S85 Carbon Plenum is more than a component — it’s the beating heart of the legendary V10, reimagined. By fusing cutting-edge materials with factory-engineered precision, Eventuri has created a plenum that captures what makes the S85 so iconic: response, resonance, and raw emotion.
