HKS Cold Air Intake & Racing Suction Full Kit - WRX STi

• Designed as an upgrade item exclusively for racing suction. By completely separating the engine compartment from the air cleaner, fresh air can be constantly introduced for stable performance.
• The cleaner box cover and duct cover are made of carbon fiber and manufactured by the vacuum infusion method, which is almost as light and strong as the autoclave method. The surface of the carbon cloth is a 3k twill weave to dress up the engine bay.
• 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 exotic 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 performance.
• Kit includes Super Power Flow and Aluminum Suction pipe. Polished aluminum pipe improves engine room appearance.
• Enjoy a distinctive induction sound.
• Improving an air intake efficiency, HKS changed from flexible stock rubber hose to aluminum pipe. This significantly reduces an airflow restriction at an HKS flow bench test compared to the stock intake system.
  Removable air duct (air guide) which has a wide opening is newly designed. This can be directly used stock ECU even for the normal vehicle or the vehicle with a custom muffler. You can reduce more air intake resistance, removing the air guide. (*)
  (*) ECU setting is required when combination use of the metal catalyzer or removing the airflow adapter guide.

This full kit has been designed to provide the ultimate air-intake performance from a direct bolt-on application. The cold air intake box is manufactured with dry carbon fiber designed to supply the intake system with an abundant supply of high quality air. The racing suction system has been developed as the top of the line air induction system for real sports applications. In addition to air filter these kits come with redesigned intake piping to further enhance induction efficiency. A great item that will help provide the most potential with each further step up enhancement along with a sporty intake sound. Superior quality materials used that also provide an overall reduction in weight and add an amazing dressup style to the engine bay.
