SF Airbox (716100) - 2018 WRX STi Type RA / 2019-2021 WRX STi
Upgrade your COBB SF Intake with the COBB SF Air Box, designed to bring the benefits of a true cold air intake to your setup. By enclosing the SF Intake and utilizing the factory inlet snorkel to pull fresh air from the front grill, this airbox blocks horsepower-robbing hot engine bay air. Its unique design also separates rainwater to prevent the water ingestion issues typical of in-fender cold air intakes. Constructed from durable 16-gauge aluminum with a one-piece surround, directional lid, and stainless steel hardware, it delivers a seamless, OEM-quality fit and finish. This kit also includes a new Subaru OEM Air Duct required for compatibility with the 2018 STI Type RA and 2019-2020 STI.
Emissions Note: This part is 50-state legal for sale and use on emission-controlled vehicles under CARB EO D-660-106.
