• The cleaner box is made of fiberglass and individually created by skilled artisans using the hand layup method.
• The combination of matte carbon and black color make the beautiful engine bay with exoic car vibes.
• It does not spoil the "open" sports sound that comes from the sound of air rushing into the intake.
• Compared the intake air temperature using WLTC mode on a chassis dynamometer that can control the room temperature regardless of environmental conditions.
• While maintaining the intake efficiency of the open type racing suction, the cold air intake can keep the intake air temperature stable and lower than that of the stock air cleaner.
• Cold air intake will supply cooler air to the turbocharger and greatly contribute to improved and performance.
