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

The Eventuri BMW E9X M3 Black Carbon Inlet Plenum is a purpose-built upgrade engineered to enhance the acoustic character of BMW's naturally aspirated S65 4.0L V8 engine while preserving factory performance dynamics. Designed specifically for the E9X M3 platform, this carbon plenum replaces the OEM plastic unit with a motorsport-inspired solution that draws out the unmistakable induction sound signature of the high-revving V8.

Manufactured entirely from prepreg carbon fiber construction including the internal trumpets, the Eventuri plenum maintains the precisely calculated internal volume and runner geometry developed by BMW engineers. Through extensive testing, Eventuri optimized the carbon layup to produce a refined resonance profile that delivers a sharper, more pronounced induction tone as RPM builds, capturing the raw character enthusiasts expect from the S65 without disrupting mechanical balance or smooth power delivery.

The plenum features CNC-machined aluminum flanges engineered for precise fitment and seamless integration with both factory and upgraded intake systems. An integrated CNC-machined temperature sensor boss maintains OEM sensor compatibility while an integrated CNC-machined breather boss preserves factory crankcase ventilation function. The carbon fiber plenum base and lid are bonded as a single assembly for structural integrity and consistent performance.

The matte carbon fiber finish delivers a subtle, technical motorsport aesthetic that pairs with OEM and OEM-plus engine bays while providing a substantial upgrade over the factory plastic unit. Unlike gloss carbon, the matte finish offers an understated appearance while still showcasing the precision carbon fiber construction throughout the plenum and internal trumpets manufactured to factory specifications.
