NOTES

• Racing Suction (70020-AF108) & Cold Air Intake Box (70026-AF005)

APPLICATIONS

• Subaru WRX/STi 4D (2015, 2016, 2017, 2018, 2019, 2021)

FEATURES

• Designed specifically for racing suction as an upgrade item. Fresh air can be introduced continuously for stable performance by entirely separating the engine compartment from the air cleaner.
• 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 makes 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.
