Are Carbon Fiber Plenums worth it?
Short answer: yes.
Long answer: it is the best driving experience modification on the E9X M3. 

Here's why.

The S65 is a masterpiece: it is the heart, soul, and backbone of the E92 M3 - without, it may as well be another 335i with a few bits and bobs. 

Unicity. 

Yet, Germans subdued the experience with sound deadening as it aimed at building a GT car first. As 15 years are now gone, we value the E92 M3 for its rawness hidden right below its coat. 

The Carbon Plenum is like seeing your wife moving from pyjamas to a dress: it exposes the flattering charms, fierceness of her character, and it does it with class. 

If you thought downshifts sounded good, you haven't heard anything yet. 

You control it the madness with your right feet. 

It is forever grin inducing.

Unlike an exhaust system: a Carbon Fiber Plenum has no drone, no booming.

The OG Connex: CarboProject GmbH

With the recent release of numerous carbon fiber plenum options, I had been recently looking at carbon fiber plenum options for my E92 M3 and dove deep into European M3 forums in UK, France & Germany. I was surprised to see they had actually been around for a while in one form or another.

I reached out to René at CarboProject - a high end carbon fiber manufacturer in Germany. He has been making custom carbon fiber plenums for the E9X M3 since it came out in 2007.

CarboProject's Carbon Fiber Plenum for the S65 V8

The CarboProject Carbon Airbox is developed with the OEM plastic ITB fittings with an enlarged upper pre-preg carbon lid for the enhanced sound we're all looking for.

I love the box due to its amazing sound, various options, its OE fitment and reliability, along with the more Motorsport look of the lid versus current options.

His carbon fiber plenum had initially been developed in 2007. As the community started adopting the product en masse, we provided feedback - and he listened.

The community feedback has helped improve the product with no-cost options such as Matte Clear Coat, Flat Top finish and the infamous Export version with the thinner, pre-preg, carbon fiber lid for improved induction noise. 

EuroConnex exclusively offers the Export version to members worldwide.
