O.S. Engine OS44969430 Intake Manifold FSa-110-P  [OS44969430]

Intake Manifold for FS Engines

The O.S. Engine OS44969430 intake manifold FSa-110-P is an RC-scale replacement part intended for use with O.S. FS series engines, serving to route and stabilise incoming air and fuel mixture to the carburettor area. It is supplied as a single intake component and is described here as a straight technical replacement without making broader claims about modifications or performance gains.

Installation notes: inspect the manifold sealing surfaces for wear or damage before fitting, ensure mating faces are clean, and tighten mounting fasteners evenly to avoid warping the flange. Replace any gaskets or seals that show signs of compression or cracking to maintain proper sealing and prevent air leaks.

Tuning role: the intake manifold affects intake flow characteristics and can influence idle stability and throttle response on nitro RC engines; when diagnosing erratic idle or poor throttle transition check the manifold and associated seals as part of the routine tuning process.
