BT Moto Intake Flapper Kit for BMW S1000RR-S1000R-S1000XR (2025)

BT Moto Intake Flapper Kit for BMW S1000RR-S1000R-S1000XR (2025)

The BT Moto Intake Flapper Kit is an aftermarket bt-moto-intake-f…00r-s1000xr-2025/ ‎ modification for 2020–2025 BMW S1000 series motorcycles. It removes the factory-installed intake flappers in the airbox. These flappers were originally designed to reduce intake noise at low RPMs but inadvertently restrict airflow, leading to higher intake temperatures and reduced engine performance. The BT Moto kit replaces the flappers with billet aluminum plugs and includes a servo block-off, allowing for unrestricted airflow and more consistent engine performance.

⚙️ Key Features

• Unrestricted Airflow: By removing the factory flappers, the kit ensures that fresh, ambient air enters the airbox at any speed, RPM, or gear, eliminating the bottleneck caused by the OEM design.

• Consistent Power Delivery: The modification leads to more consistent power across the entire RPM range, reducing the delays in ignition timing caused by the heat soak from the factory airbox flappers.

• Improved Throttle Response: Riders report sharper throttle response, especially in lower gears and at lower speeds, enhancing the overall riding experience.

• Enhanced Induction Sound: The removal of the flappers results in a more aggressive and race-inspired intake sound, adding to the auditory appeal of the motorcycle.

• High-Quality Components: The kit includes billet aluminum plugs and a servo block-off, ensuring durability and a precise fit.
