HKS Racing Cold Air Intake Kit w/ Dry Carbon Surround 2015-2021 STI
Here, you are looking at the HKS Racing Cold Air Intake Kit w/ Dry Carbon Surround for your 2015-2021 STI.
By completely separating the engine compartment from the air filter, fresh air can be constantly introduced for stable performance.
The filter cover and duct cover are made of carbon fiber, which is almost as light and strong as the autoclave method.
The 3k twill weave carbon fiber surface of the airbox is absolutely breathtaking, and a great was to dress up the engine bay. The box is made of hand-laid fiberglass with a carbon fiber shell surrounding it. The combination of matte carbon and black color gives the engine bay exotic car vibes. Despite its air-tight construction, It does not spoil the “open” sports sound that comes from the sound of air rushing into the intake.
HKS went as far as to compare the intake air temperatures of this kit against the standard Racing Suction kit without a box using WLTC mode on a chassis dynamometer, which can control the room temperature regardless of environmental conditions.
While maintaining the intake efficiency of the open-type racing suction, the carbon box allows this cold air intake to keep the intake air temperature stable and lower than that of both the stock air cleaner and standard racing suction kits. This cold air intake will supply cooler air to the turbocharger and greatly contribute to improved performance.
Please note, this kit will require a re-tune of your vehicle.
