The intake boot is a flexible piece that connects the intake manifold to the air filter box. It is made from a durable, heat-resistant material and is designed to provide a good seal to ensure proper air flow to the carburetor.

The intake gaskets are included in the kit to ensure a proper seal between the intake manifold and the cylinder head, as well as between the carburetor and the intake manifold. These gaskets are made from a high-temperature, heat-resistant material to ensure a long-lasting seal.

The WR250F 03-05 Keihin FCR Carburetor Intake is a direct replacement for the stock intake system on the Yamaha WR250F motorcycle and is easy to install. It is suitable for off-road use and is designed to provide improved power output, better throttle response, and increased fuel efficiency.
