Karbonius Composites Carbon Engine Cover for G90 & G99 BMW M5

Karbonius Composites brings the same in-house engineering and craftsmanship behind the legendary E46 M3 CSL airbox to this vented Carbon Engine Cover for the G90 BMW M5 sedan and G99 M5 Touring, delivering an OEM-quality upgrade that integrates cleanly into the engine bay. Produced entirely in Spain, every step is handled internally – from 3D scanning and toolmaking to pre-preg carbon layup, autoclave curing, robotic trimming, clear-coat finishing, and final quality control – for consistent fit and finish. This listing is for the vented engine cover only (not the full engine cover package), constructed from 100% pre-preg (dry) carbon fiber and autoclave-cured for high strength, low weight, and a uniform surface. With integrated mounting tabs for OEM-level fitment and a motorsport-inspired vented design, it’s available in 2×2 twill gloss or 2×2 twill matte clear to match surrounding OEM and aftermarket carbon components.
