When Karbonius develops a product, no half measures are allowed. So when it turned its attention to the intake system of the S65 engine (as found in the E90 M3, E92 M3 and E93 M3), the end result had to improve the engine efficiency, sound and, at the same time, the appearance inside the engine bay.

The Karbonius S65 airbox system has been designed using the most modern technologies with analysis in 3D and in 2D . Karbonius have re-designed the genuine airbox, intake elbow and the air filter cover, managing to optimize the air flow that enters the engine and simultaneously to minimize the turbulences inside the airbox system, with the consequent gain of power; all in beautiful pre-preg carbon fibre. Besides this gain of power, the Karbonius Intake System gives the engine an awesome appearance and an astonishing sound, and finished with high gloss varnish with UV protection. Over 3kg in weight savings, too.
The ‘M/V8 Version’ of this box comes with the gap for the originals M and V8 badges (not included).
