Introducing the E9X M3 Matte Carbon Fiber Plenum from Eventuri. Made from 100% high-grade prepreg carbon including the internal trumpets, this plenum replaces the stock plastic version and unleashes the roar of the naturally aspirated BMW V8 engine. Since the trumpet lengths are tuned by BMW to the internal volume, changing this could result in a loss of performance so we kept the same volume to not upset the way the car drives in terms of power delivery. Although there isn’t a performance gain from the carbon plenum, the induction sound generated takes the driving experience of the M3 to a whole new level. The raw V8 rumble gives the M3 an almost CSL-like sound and is truly an intoxicating experience. We went through several iterations using different carbon thicknesses to fine-tune the sound and the resulting plenum generates an almost unbelievable induction volume and tone.

*Some images are shown with the optional Matte Carbon Intake and Airbox Lid. The "M" and "V8" badges are optional. 

Each Plenum consists of:

  • Carbon Fibre base and Lid
  • 8 x Carbon trumpets with OEM specifications
