O.S. Engine OS44969400 Intake Manifold FSa-110 for FS-Series Engines  [OS44969400]

Replacement intake manifold for FS-series engines

This RC intake manifold is listed as O.S. Engine OS44969400 FSa-110 and functions as the intake connection for FS-series glow engines. It is supplied as a direct replacement intended for hobby-grade model engines that use the FSa-110 designation.

The manifold channels the fuel and air from the carburetor to the engine intake flange while keeping alignment and a seal at the mounting interface. When replacing this item, verify flange orientation and check the sealing surfaces on both the manifold and engine to avoid air ingress.

Installation notes: where possible fit using the engine's original mounting hardware, inspect any gaskets or O-rings for damage prior to assembly, and tighten fasteners evenly and progressively to prevent flange distortion. Small alterations in intake geometry can change throttle response and mid-range delivery, so run the engine after fitting and fine tune the carburetor as required.
