This replacement air cleaner box optimizes the intake layout to lower air temperature and draw in denser air, enhancing volumetric efficiency in the cylinders for increased power output. By upgrading the filter material and redesigning the air box shape, it reduces intake air resistance by approximately 19%. Utilize the separately available filter maintenance kit (90000-YZ0-5000-99) to clean and reuse the filter repeatedly.
