The Karbonius E9X M3 (S65) Carbon Inlet Plenum and Intake System is the most complete carbon intake solution available for BMW's naturally aspirated V8. Where BMW never developed a carbon plenum for the S65 (as they did for the S54 CSL), Karbonius engineered a full carbon fiber intake system — plenum, elbow, airbox cover, and air filter — to improve engine efficiency, unlock a dramatic induction sound, and transform the engine bay aesthetic.

Designed by Karbonius' in-house engineering team using modern 2D and 3D flow analysis, every component has been redesigned to optimize air flow into the engine while minimizing turbulence inside the airbox — delivering measurable power gains alongside the visual and auditory upgrades.

Each piece is manufactured from 100% prepreg carbon fiber and autoclave-cured in Spain under ISO 9001 quality standards, combining motorsport-grade construction with authenticity and long-term durability.

  • Carbon inlet plenum
  • Carbon elbow
  • Carbon airbox cover
  • BMC high-flow air filter (BMC 536/08; verify compatibility with your filter cartridge)
  • Installation tools

Product Details
