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 reached out to René at CarboProject. He has been making custom carbon fiber plenums for the E9X M3 and E60 M5 since it came out in 2007. I organized Group Buys and Curated Specials to provide the BMW M community with over 100 plenums since launching the Connex.

OEM + Carbon Fiber Plenum for the S85 V10
The CarboProject Carbon Plenum is developed with the OEM plastic ITB fittings with an 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 with the matte clear coat finish option.
NEW Summer 2021: Export Sound Variant
Following on the product improvements made to the E9X M3 S65 carbon fiber plenum, the S85 variant is now available in the Export sound configuration.
The community feedback has helped improve the product with infamous Export version. The center sections of the plenum are thinner for enhanced induction noise while the edges of the carbon fiber lid remain at standard thickness measurements for long term reliability.
