O.S. Engine OS44369400 Intake Manifold FSa-72 Direct Replacement  [OS44369400]

Manifold suited to FS-series applications

This intake manifold is an RC-scale engine part intended for use with O.S. FS engine components.

It is designed as a direct-replacement intake route that supports practical installation and tuning activities on small glow engines, serving primarily as a mounting and airflow component rather than a performance-enhancing accessory.

Installation notes: fit the manifold to the engine flange and secure at the manifold mounting points, ensure any gasket is correctly seated or replaced if necessary, and verify throttle linkage clearance before running the engine to avoid common fitment issues.

Tuning role: the manifold keeps an even airflow path and stable mounting which helps maintain carburetor alignment and consistent idle characteristics when performing needle adjustments or fuel mixture checks.
