Boost Bottle is designed to work with stock intake manifolds, stock manifold included.

Improves Low RPM power and Low end throttle response.

Boost Bottle enhances throttle response by storing an extra charge of the air/fuel mixture behind the reed valves for immediate use when the throttle is open. For example when you sudden turn full the throttle at start or after the corner, the air inside the bottle can provide enough air to the carburetor for mixture. Prevents it from not enough air provided by the air filter as the air from air filter is limited when the throttle is suddenly full.
