Eventuri Black Carbon Fiber Inlet Plenum Gloss for BMW M3 2008-2013

The Eventuri BMW E9X M3 Carbon Inlet Plenum is a precision-engineered upgrade developed specifically for the high-revving 4.0L S65 V8 engine. This motorsport-grade component replaces the factory plastic plenum while preserving the carefully engineered internal volume and runner geometry established by BMW, delivering enhanced induction sound and engine bay presence without compromising the engine's mechanical balance.

Rather than pursuing marginal peak horsepower gains, Eventuri focused development on maintaining the S65 engine's smooth torque delivery and throttle response while unlocking a more pronounced intake tone. Extensive testing allowed engineers to refine the carbon layup thickness to achieve an ideal resonance profile that amplifies the induction character as engine speed climbs, producing a sharper, more aggressive sound reminiscent of the iconic M3 CSL.

Constructed entirely from prepreg carbon fiber with a high-gloss finish, including the internal trumpets manufactured to factory specifications. The carbon fiber plenum base and lid are bonded as a single assembly, replacing aging plastic components with a finish engineered for BMW's last naturally aspirated V8 M3 platform.

The plenum integrates CNC-machined aluminum flanges for precise fitment alongside an integrated CNC-machined temperature sensor boss and breather boss. Carbon fiber trumpets maintain OEM plenum volume and trumpet geometry to preserve the engine's smooth performance characteristics. Compatible with factory and upgraded intake systems, this component delivers seamless integration into the engine bay with OEM-level fitment precision.

Designed for BMW E9X M3 owners seeking to enhance the sensory experience of the naturally aspirated S65 V8 while respecting its mechanical engineering.
