Cobb 2015 Subaru STi SF Blue Intake & Air Box
SKU: C005 715315-BL
Moderate — 2–4 hours
Overview
The intake features a one-piece, high-temperature plastic composite body that offers superior heat rejection compared to metal designs, helping to keep intake air temperatures cooler. The integrated airbox utilizes the factory Subaru snorkel to draw in cold air, preventing hot engine bay air from entering the system and also safeguarding against rainwater ingestion, a common issue with in-fender cold air intakes.
