Eventuri Carbon Fiber Plenum E9x S65 M3

A must have mod for all E9x M3s! Fitment: 2008-2011 E90 M3                2008-2013 E92/E93 M3 This E9X M3 Carbon Fiber Plenum is made from 100% high grade prepreg carbon including the internal trumpets, and 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.  Each Plenum consists of: Carbon Fiber base and Lid 8 Carbon trumpets with OEM specifications 8 CNC machined aluminum flanges CNC machined temperature sensor boss CNC machined breather boss
