Product Description

The K&N KA-1406 is a premium high-flow replacement air filter engineered for performance motorcycles such as the Kawasaki Ninja ZX-14 / ZZR1400 and the Concours 14 / 1400GTR. Using layered, pleated cotton-gauze media, it dramatically boosts airflow compared to stock paper filters while still offering superior filtration against dust and contaminants. Riders can expect improved throttle response, potentially better horsepower and torque, and more responsive engine behavior under load.

Installation is straightforward - KA-1406 drops directly into the OEM airbox and seals securely thanks to the application-specific sealing bead and base design. For standard engine configurations, no fuel-management tuning or modifications are required. The filter is washable and reusable, making it a cost-effective upgrade for long-term ownership. For riders who value performance without sacrificing protection, KA-1406 offers a durable, reliable, and maintenance-friendly alternative to disposable filters.
