Product Description

The RK-3940 High-Flow Air Intake System from K&N is a direct-fit performance upgrade for the Yamaha XVS950 Bolt lineup (2014-2022). By replacing the restrictive stock air cleaner with a custom aluminium backing plate, integrated velocity stacks, and a high-flow cotton gauze filter, the RK-3940 dramatically improves airflow to the engine - which can translate into enhanced throttle response, stronger torque delivery, and a noticeable horsepower boost of approximately 7.14 HP under ideal conditions. Installation is straightforward and requires no modifications, thanks to the included mounting hardware.

The filter is washable, reusable, pre-oiled and ready to install, making it a low-maintenance upgrade that offers long-term value over disposable filters. Its durable construction and powder-coated metal housing also add a clean, premium look to your bike's intake. For riders who demand more performance and a more responsive ride from their Bolt without compromising durability or requiring complicated modifications, RK-3940 is a solid choice.
