O.S. Engine OS44969400 Intake Manifold FSa-110  [OS44969400]

Intake manifold for FS engines

This RC-scale intake manifold is listed as O.S. Engine OS44969400 FSa-110 and serves as the intake connection for FS-series glow engines. It is presented as a direct replacement part intended for use on hobby-grade model engines where the FSa-110 designation applies.

Functionally the manifold routes the fuel/air mixture from carburetor to the engine intake flange while maintaining alignment and sealing at the mounting interface. When servicing or replacing this component, confirm flange orientation and the sealing surface condition on both the manifold and engine to prevent air leaks.

Installation notes: install using the engine's original mounting hardware where possible, inspect any gaskets or O-rings for damage, and tighten fasteners progressively to avoid distorting the flange. As with other RC engine intake parts, small changes in intake geometry can influence throttle response and mid-range behavior, so check engine behavior after fitting and make minor carburetor adjustments if needed.
