Description
Overview:
The Inlet/Exhaust Manifold is a genuine BSA component for the BSA 420CC industrial engine. It is a combined manifold that manages both intake airflow to the cylinder and evacuation of exhaust gases, helping the engine breathe correctly and run reliably under load. Manufactured in robust cast iron with flanged mounting faces, it is engineered for long service life and stable sealing when used with the correct gaskets and fixings. As an unused old-stock vintage part, it may show light storage marks or tarnishing, but it remains a sound, factory-spec replacement for maintenance or restoration work. Ideal for site machinery powered by the BSA 420CC, this OEM manifold supports dependable performance in generators, pumps, compressors and other small plant.
Key Features:
- Genuine BSA part for assured fit and quality on the 420CC industrial engine
- Direct replacement for OEM No. 86 790, matching original geometry and port alignment
- Durable cast-iron construction for heat resistance and long service life
