The OG Connex

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.

Building upon the E9X M3 S65 Carbon Fiber Plenum

Made with 100% in prepreg carbon fibre in their facilities in Germany, this 2 piece
front air duct is made in 2x2 carbon weave and is cured in autoclave.

The weave is designed to match the S65 Carbon Fiber Plenum  - it it oriented at 3 o'clock, top right of an imaginary square for my visual guys out there looking to match this with carbon components from other brands. 

The product is clear coated in 2 component hardened clear coat for a durable finish and resistant to the high temperatures of the engine bay. It is available in Gloss or Matte finish. 


  • 100% carbon fibre pre-preg
  • Made in Germany
  • 2x2 weave
