Introducing the Eventuri E9X M3 Carbon Fibre 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 Eventuri 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. Eventuri 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. It is also now available to be ordered with a Gloss or Matte carbon fibre finish (select one).

The Eventuri E9x M3 Carbon Plenum consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standards.
