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.

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:

Data Logging Flow and Inlet Temperature

To monitor and record data output from the ECU we used a Bavarian Technic diagnostics tool. The car was fitted with the stock system and then data was logged in 4th gear to the redline. Then the Eventuri intake was fitted and the same method applied. The outputs show that the air mass flow with the Eventuri is higher across the entire RPM range – with a bigger difference at higher RPM where the restrictions in the stock system become more apparent. Furthermore the difference between the ambient temperature and the inlet air temperature (IAT) is also smaller with the Eventuri due to the scoop enabling a higher air speed through the airbox. Here are 2 screenshots of the data output, one at approximately 5000rpm and the other at approximately 8300rpm.

Data Logging summary:

  • 5000rpm IAT difference with ambient: Stock intake = 9.6 Degrees C : Eventuri = 5.3 Degrees C
  • 8300rpm IAT difference with ambient: Stock intake = 7.6 Degrees C : Eventuri = 4.7 Degrees C
  • 5000rpm Air Mass Flow Rate: Stock intake = 635 kg/h : Eventuri = 650 kg/h
  • 8300rpm Air Mass Flow Rate: Stock intake = 1168 kg/h : Eventuri = 1202 kg/h
