Feiya takes high-performance manufacturing to the next level with this CNC ported cylinder head. Unlike standard cast ports which may contain minor surface irregularities or core shifts, this unit undergoes a specialized secondary machining process using advanced 5-axis CNC centers. We digitally carve the intake and exhaust ports to an exact, computer-optimized profile. This process ensures that every cubic millimeter of material is removed precisely according to the flow-bench tested design, eliminating the inconsistencies inherent in traditional hand-porting methods.
The primary advantage of this technology is airflow uniformity. By precisely controlling the cross-sectional area and surface texture of the runners, we increase the velocity of the air-fuel mixture without sacrificing low-end torque. The intake ports are machined to promote better fuel atomization, while the exhaust ports are smoothed to expedite gas scavenging. This results in a cylinder head that delivers a significant improvement in volumetric efficiency, translating directly to sharper throttle response and higher peak horsepower. It is the ultimate choice for racing teams and performance enthusiasts demanding identical flow characteristics across every production unit.
