The heat sink effect helps to cool the engine. The genuine part's fins were oriented vertically, disregarding the flow of air, whereas this product is designed to actively utilize the airflow. The higher-end models also feature additional heat dissipation fins on top for improved heat dissipation.
You can feel that the engine temperature rise is suppressed more than with the genuine product when cruising under high load. It excels not only in fashion but also in functionality. The main body is made from machined aluminum, giving it a premium feel.
