Description
Overview:
The Cylinder Head suits Jap Engines is a Genuine JAP part designed to restore and maintain compression, cooling and sealing performance on classic J.A.P. stationary and small plant petrol engines. It is an OEM-spec head (OEM No. 21935) with a robust cast-metal construction and prominent cooling fins to dissipate heat effectively in air‐cooled applications. Machined gasket faces and correctly positioned fixings help ensure a reliable seal with the cylinder barrel.
