The Boyesen Rage Cage Carburetor Boot RB-18A is a high-performance intake component designed for compatible snowmobile applications. Manufactured by Boyesen, this carburetor boot is engineered to work with the Rage Cage reed valve system, helping deliver consistent airflow from the carburetor into the engine. Its integrated, seamless Tenzalloy chamber provides a durable, streamlined passage for the air charge while supporting reliable performance in demanding riding conditions.
Designed with aerodynamic directional dividers, the Boyesen RB-18A channels incoming air evenly through the intake system. The patented, dyno-proven design creates rapid air movement with reported velocities of up to 500 MPH, helping maintain maximum flow across the engine's RPM range. This improved air distribution can support crisp throttle response, strong acceleration, and consistent engine operation when properly matched to the snowmobile's application.
The RB-18A is supplied as a carburetor boot replacement for compatible Boyesen Rage Cage snowmobile systems. Confirm vehicle, engine, carburetor, and reed cage compatibility before installation, as fitment varies by application. Rage Cage kits are sold per engine, replacement reeds are sold per cylinder, and replacement carburetor boots are sold per carburetor; order one RB-18A boot for each compatible carburetor requiring replacement.
