Karbonius G90 / G99 M5 Carbon Fiber Engine Cover Kit

Karbonius Carbon Fiber Engine Bay Kit for BMW M5 G90 / G99

Stand out from a crowded carbon market with Karbonius, hand-built in Spain by the artisans behind the legendary E46 M3 CSL airbox. Unlike most suppliers, Karbonius controls the entire process in-house: 3D scanning, toolmaking, pre-preg carbon layup, autoclave curing, robotic trimming, clear-coat finishing, and quality control. The result is a true OEM-plus engine bay upgrade for the BMW M5 G90 sedan and G99 M5 Touring.

Crafted from 100% pre-preg (dry) carbon fiber and autoclave-cured for strength, low weight, and a uniform surface, this kit is engineered for precise fitment with integrated mounting tabs. Available in 2×2 twill gloss or 2×2 twill matte clear, it complements the M5’s factory design with a clean, premium presentation.
