Carbonin Carbon Air Duct for BMW S1000RR K67 (2019-2022) – CB4066

A direct-fit carbon air duct engineered specifically for the BMW S1000RR K67 (2019–2022), the Carbonin CB4066 is one of those upgrades that earns its keep every time you ride. It replaces the stock plastic ducting with a lightweight carbon unit that improves airflow to the engine, making a genuine difference to throttle response and overall efficiency whether you are commuting, touring or pushing on at the weekend.

Key Features

• Precision-fit design for the BMW S1000RR K67 (2019–2022) — drops straight in with no modification required
• High-grade carbon construction reduces weight without any compromise to structural rigidity or long-term durability
• Optimised internal geometry channels air more efficiently to the engine, supporting improved combustion and throttle response
• Race-proven Carbonin manufacturing standards deliver a surface finish and panel accuracy that holds up in both daily and track use
• Straightforward installation keeps labour time to a minimum, making it a practical upgrade for owner-fitted maintenance

Build Quality and Everyday Usability

Carbonin manufactures this air duct to the same exacting standard as its track fairing kits, meaning the carbon weave is consistent, the resin saturation even, and the trimmed edges clean. On a bike you ride regularly, that matters — there are no rough edges to catch wiring looms, and the fit against adjacent bodywork is tight enough to prevent the buffeting and vibration that poorly fitted ducting can introduce over time.

The weight saving over the OEM plastic part is a genuine benefit even on a road-spec S1000RR. Less unsprung and ancillary mass contributes to the bike's agile character, and the carbon resists the heat cycles and UV exposure that cause standard plastic components to discolour and become brittle after a few seasons.

Performance Rationale

The CB4066 duct is shaped to maximise the volume and velocity of air reaching the intake. On the K67-generation S1000RR, the airbox relies on ram-air pressure that builds with road speed; a well-profiled carbon duct feeds that system more consistently than the original moulding, which is why the upgrade is popular with riders who want a noticeable improvement without remapping or engine work. The gains are modest at road speeds but stack usefully with other intake and exhaust modifications.

Fitment and Compatibility

This air duct is designed exclusively for the following model:

• BMW S1000RR K67 — model years 2019, 2020, 2021, 2022

It is not compatible with earlier K46-generation S1000RR models. If you are unsure of your bike's generation, check the frame identification plate or confirm via your VIN before ordering.
