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

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 serves as the airflow passage between the carburettor inlet and the engine crankcase, offering a direct-fit option for repairs or setup changes without implying real vehicle use.

The design focus is on consistent fit and serviceability: verify model number OS42569400 before purchase, inspect mating surfaces and gaskets during installation, and confirm clearance around the carburettor and needle assembly. The manifold affects throttle response and is one element in overall engine tuning, so changes should be evaluated alongside carburettor and exhaust adjustments.

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

As a direct-fit RC-scale intake manifold for FS-series engines, this part is intended for routine replacement or setup changes where fit and airflow routing are the priorities; confirm OS42569400 before fitting.
