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

FS Engine Replacement Intake Manifold

The O.S. Engine OS44969430 intake manifold FSa-110-P is an RC-scale replacement part for use with O.S. FS series engines, routing and stabilizing the incoming air and fuel mixture to the carburettor area. It is supplied as a single intake component and presented as a direct replacement without broader claims of modified performance.

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 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 routine tuning checks.
