Karbonius Carbon Fiber Plenum (Full System) for E9x M3

The KARBONIUS S65 AIRBOX has been designed by the engineering team using the most modern technologies with both 3D and 2D analysis. We have re-designed the genuine airbox, the intake elbow, and the air filter cover, managing to optimize the air flow that enters the engine and simultaneously minimize the turbulence inside the airbox system, resulting in increased power.

In addition to the power gains, the Karbonius Plenum and Intake System gives the engine a phenomenal appearance and an astonishing sound, finished in high gloss varnish with UV protection.

Karbonius Composites holds their products to the highest standards. Made entirely with 100% prepreg Carbon Fiber in their facilities in Spain under ISO 9001 Management Quality System rules by qualified staff.
