FS Engine Intake Manifold OS42569400 FSa-155-P for O.S. Engine  [OS42569400]

Replacement intake manifold for FS engines

This intake manifold is an RC-scale replacement part designed to interface with O.S. Engine FS-series engine assemblies. It creates the airflow passage between the carburettor inlet and the engine crankcase and is offered as a direct-fit choice for repairs or setup changes without implying use on full-size vehicles.

Design priorities are consistent fit and serviceability: confirm model number OS42569400 before ordering, inspect mating faces and gaskets during installation, and verify clearance around the carburettor and needle assembly. The manifold will influence throttle response and should be considered alongside carburettor and exhaust adjustments when tuning the engine.

Installation notes: replace any damaged gaskets, align the manifold to the engine flange, and tighten fasteners evenly to avoid misalignment. If you are unsure about compatibility with a specific FS-series variant, contact the seller or consult manufacturer documentation for confirmation.

This direct-fit RC-scale intake manifold suits FS-series engines when fit and airflow routing are the priorities; always verify OS42569400 before fitting.
