The Eventuri BMW E9X M3 (S65) Black Carbon Inlet Plenum – Gloss is a meticulously engineered upgrade designed to enhance the sensory experience of BMW’s legendary naturally aspirated V8 while preserving its factory-tuned performance characteristics. Crafted entirely from premium pre-preg carbon fiber—including the internal trumpets—this M3 carbon inlet replaces the OEM plastic plenum with a visually striking and acoustically rewarding alternative.

BMW engineered the S65 V8 with carefully calculated internal volume and trumpet lengths to ensure smooth power delivery and strong response throughout the rev range. To maintain this balance, Eventuri retained the original specifications, ensuring the Eventuri M3 carbon inlet plenum does not compromise drivability or low-end torque. Instead of chasing peak horsepower numbers, the focus of this upgrade is to amplify the induction character that defines the E9X M3.

Through extensive development and testing, Eventuri refined the carbon layup thickness to achieve an optimal resonance profile. The result is a dramatically enhanced induction sound that builds with RPM, delivering a raw, motorsport-inspired tone that recalls the character of the M3 CSL. While outright performance gains are not the objective, the transformation in sound elevates every drive and reinforces the emotional connection to the S65 engine.

The Eventuri BMW E9X M3 (S65) Black Carbon Inlet Plenum – Gloss is compatible with the factory intake system as well as optional carbon intake components, allowing owners to tailor their setup while maintaining OEM fitment standards. Beyond sound, this plenum also delivers a substantial visual upgrade, replacing aging plastic with high-gloss carbon fiber worthy of BMW’s V8 M flagship.

Note: Some images may show optional carbon intake components. M and V8 badges are available separately.
