HKS Cold Air Intake Box Kit VAB Subaru WRX | STI 2015-2021

Highly effective intake system designed for HKS Racing Suction to increase flow of cold and oxygen dense air to the engine. It can reduce intake air temperature for improved combustion, increased power output, and improved throttle response.Features: Developed as a competition upgrade, this item enables absolute separation of the engine compartment from the air filter for dependable constant fresh air supply. The box and duct covers are crafted from carbon fiber and made with a vacuum infusion process, which is nearly as efficient for both lightness and strength as the autoclave method. This product features a 3k twill weave surface to add a stylish touch to 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.
