O.S. Engine OS42569400 Intake Manifold FSa-155-P compatible with FS engines  [OS42569400]

RC intake manifold designed for FS-series setups

This component is an RC-scale intake manifold intended to mate with O.S. Engine FS-series engine assemblies. It routes air from the carburettor inlet to the crankcase and is supplied as a direct-fit option for replacement or configuration changes without reference to full-size applications.

Engineers focussed on repeatable fit and easy servicing: verify OS42569400 before purchase, examine the mating surfaces and gasket condition when fitting, and confirm there is adequate clearance around the carburettor and needle assembly. Changes to the manifold will influence throttle characteristics and should be tested together with carburettor and exhaust settings.

Fitment guidance: use fresh gaskets where needed, align the flange carefully, and tighten bolts progressively to prevent distortion. For questions about compatibility with a particular FS-series submodel, check with the vendor or official documentation.

As a direct-fit intake manifold for FS engines, this part prioritises correct routing and fit; always confirm OS42569400 before installation.
