Cylinder Heads, found within the Engine Parts > Heads & Valve Train section, are critical components responsible for sealing the cylinders of an engine and housing the valves, spark plugs, and fuel injectors. Positioned above the engine block, these parts facilitate the combustion process essential for vehicle operation in passenger cars and commercial vehicles. Cylinder Heads are precision-engineered from materials like cast iron or aluminum alloy to withstand high temperatures and pressures. Key characteristics include port design for optimal airflow, combustion chamber shape, and valve seat angles - all impacting engine performance and efficiency. Examples in our catalog include Scania cylinder heads (MPN 2609859), Febi heads (MPN FEBI48312, FEBI44202) and those for Mercedes-Benz Trucks, alongside options from Bosch like MPN F01M101781.
