O.S. Engine OS44969430 FSa-110-P Intake Manifold for FS Series Engines  [OS44969430]

Replacement Manifold for FS Engines

The O.S. Engine OS44969430 intake manifold FSa-110-P serves as an RC-scale replacement for O.S. FS series engines, guiding the air and fuel mixture toward the carburettor. It is supplied as a single component and described here strictly as a direct technical replacement rather than a performance modification.

Installation notes: check the manifold sealing faces for wear before installation, clean all contact areas, and tighten mounting fasteners evenly to avoid flange distortion. Replace any degraded gaskets or seals to ensure a consistent seal and prevent unwanted air ingress.

Tuning role: intake geometry can influence idle behaviour and throttle transitions; include the manifold and its seals when investigating unstable idle or hesitation during throttle changes as part of standard tuning checks.
