Eventuri BMW E9X M3 (S65) Carbon Inlet Plenum

$2,104.25 $2,215.00
Introducing the E9X M3 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 shown with the optional Carbon Intake and Airbox Lid. M and V8 badges are optional.

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

Phenomenal Induction Sound, Amazing Quality

Extremely difficult to find an Eventuri Plenum for the E9x platform right now; most places quoting the end of November at the earliest. Not only did ACM have one, I had it in my hands within a week of purchasing despite being halfway across the country. No games with getting the part from some intermediary or sister company, just plain, direct, honest-dealing. The plenum itself is phenomenal. The depth and clarity of the S65’s induction noise after install is outstanding. Install itself has a few steps (remove cowl, remove strut braces, etc.), but is about as easy as it get. If I ever get another E9x in the future, the plenum will be my first mod, hands down.

Best mod

One of the best mods I’ve done on my car, even more enjoyable than an exhaust.

Perfect part, you will get the real S65.

Great service from Autocouture. Parts were on stock! Fitment of the parts is perfect. With the plenum, I have a different vehicle on demand. Smooth and decent during normal driving, but the concerto starts at WOT at higher RPM. There is an amazing engine in the front of the car and the 8 single throttle bodies really come to live with the plenum. What a sound.
