DESCRIPTION
The Cylinder Head (part number 3406737RX) is a critical component of an engine that sits above the cylinders and forms a combustion chamber. It provides a seal for the combustion chamber, allowing fuel and air to be compressed before ignition. The cylinder head also houses the valves, spark plugs, and fuel injectors depending on the type of engine. These components work together to control the flow of fuel and air into the cylinder, as well as expel exhaust gases once combustion has occurred. The cylinder head must be made from durable materials to withstand high temperatures and pressures within the engine. Proper maintenance of this part is crucial for optimal engine performance, including regular inspections for cracks or leaks in the gasket or valve seats.
