Replacement intake for FS-series engines

This intake manifold is an RC-scale engine component designed to work with O.S. FS engine parts.

The design is a direct-replacement intake route that supports installation and routine tuning on small glow engines, acting as a mounting and air-path component rather than a power-boosting modification.

Installation notes: align the manifold to the engine flange and manifold mounting points, check gasket seating where applicable, and confirm throttle linkage clearance before the first run to avoid common fitment problems on assembled RC powerplants.

Tuning role: the manifold preserves a consistent airflow path and mounting stability, helping maintain carburetor alignment and repeatable idle behavior when you adjust needle settings or evaluate fuel mixtures.

Which FS engines will accept this manifold?

It is made to fit engines in the O.S. FS family that share the same flange pattern; confirm your engine model dimensions against the manifold before purchase.

Should I replace the gasket when installing?

Inspect the existing gasket and replace if aged or compressed; use appropriate RC-safe gasket material and avoid permanent adhesives unless your engine manual specifies them.

Does swapping this manifold require major re-tuning?

As a direct-fit intake route, it usually preserves baseline airflow and typically only needs minor needle adjustments during a break-in or fuel check, not a full retune.
