BMW E9X M3 Carbon Plenum

Introducing our E9X M3 Carbon Fiber Plenum. 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.

This plenum can be used with the OEM airbox or any aftermarket intake system. Our own additional E9X M3 intake system provides a genuine performance gain and can be found HERE.

  • EVE-E9X-CF-PLM : BMW E9X M3 Carbon Inlet Plenum

The Eventuri E9X M3 Carbon inlet plenum is crafted from 100% prepreg carbon fiber and consists of a number of components engineered to perform a specific purpose:

Each Plenum consists of:
  • Carbon Fibre base and Lid
  • 8 x Carbon trumpets with OEM specifications
  • 8 x CNC machined aluminium flanges
  • CNC machined temperature sensor boss
  • CNC machined breather boss

A lot of attention was given to the fitment of the plenum to ensure that it fits just like OEM. The precision machined flanges allow for easy placement and installation of the plenum. Furthermore the CNC machined temperature sensor boss allows for an exact and secure fit of the sensor - just like the OEM version. No corners were cut in the development of this plenum and together with our additional E9X M3 intake system, the transformation of the car is astounding.
