Cylinder head porting
open-in-new
<p>Cylinder head porting refers to the process of modifying the <a href="/facts/Intake/JPa4RTCy">intake</a> and <a href="/facts/Exhaust_system/p7vXmU4B">exhaust ports</a> of an <a href="/facts/Internal_combustion_engine/Ju4BXzj0">internal combustion engine</a> to improve their air flow. <a href="/facts/Cylinder_head/K0RJ8mxT">Cylinder heads</a>, as manufactured, are usually suboptimal for racing applications due to being designed for maximum durability. Ports can be modified for maximum power, minimum fuel consumption, or a combination of the two, and the power delivery characteristics can be changed to suit a particular application. </p>
