DescriptionThe whole story▼
The Carbonin Avio Fiber air duct for the BMW S1000RR K67 (2019–2022) is an Italian-engineered intake component designed to deliver a smoother, more direct airflow path to the engine — giving you sharper throttle response and a more consistent power delivery across the entire rev range. Built for riders who want race-grade hardware that installs without compromise and fits as though it left the factory that way.
Key Features
- Manufactured from Carbonin's proprietary Avio Fiber composite — an exceptionally lightweight yet rigid material that resists distortion even under the sustained heat and vibration of track use
- Optimised internal geometry channels air more efficiently into the airbox, supporting improved engine breathing and overall output
- Precision-engineered to the exact dimensions of the BMW S1000RR K67 (2019–2022), ensuring a flush, gap-free fitment with no modifications required
- Designed for direct bolt-on installation — no drilling, trimming or re-routing of existing components
- Developed to professional motorsport standards, meeting the durability demands of repeated circuit sessions and long road tours alike
Construction and Material Quality
Carbonin's Avio Fiber material sits between traditional fibreglass and full carbon in the performance hierarchy — it combines the easy workability and smooth surface finish of high-grade composite with meaningful weight savings over standard OEM plastics. The result is a component that holds its shape under thermal cycling, does not flex or vibrate loose, and presents a clean visual line under the fairing of the S1000RR.
Performance on Road and Track
A poorly routed or restrictive air duct is one of the least visible yet most consequential sources of power loss on a high-revving inline-four. The Carbonin B4066AF addresses this by straightening the airflow path and reducing turbulence before air enters the airbox. Riders typically notice a crisper initial throttle response and a more linear mid-range pull — benefits that are equally welcome on a fast road ride as they are in a pit-lane stopwatch session.
Fitment and Compatibility
This air duct is designed exclusively for the following model:
- BMW S1000RR K67 — model years 2019, 2020, 2021 and 2022
