Cylinder Head

Engine Cylinder Head Functions

The functionality of the cylinder head is intricately tied to its internal structure, featuring essential components such as oil passages for continuous lubrication and cooling channels in water-cooled engines to regulate optimal engine temperature. Moreover, it plays a critical role in controlling air intake and exhaust flow, as well as managing fuel deployment. The cylinder head houses injectors and valves and typically contains more moving parts than other engine components.

What Determines the Structure of the Cylinder Head?

The structure of the cylinder head is influenced by various factors, including engine type, power requirements, cooling systems, intake and exhaust systems, along with manufacturing costs and techniques. For instance, the cylinder head of a two-stroke engine tends to be simpler compared to that of a four-stroke engine, which requires a more complex design to accommodate intake and exhaust passages.

How Much Does a Cylinder Head Cost？

A new engine cylinder head typically ranges from hundreds to thousands of dollars. However, aftermarket cylinder heads may cost significantly less, depending on factors such as engine model and machine type. OEM-quality cylinder heads can reach up to nearly $6,000 from reputable suppliers. At FridayParts, bulk ordering and large stocks allow us to pass discounts on to our customers.
