The PERRIN cold-air intake for 2016–2017 Subaru STI in Hyper Pink replaces the factory intake path to route cooler outside air to the engine. Offered as a vehicle-specific cold-air intake, it provides a visual accent in Hyper Pink while serving the functional purpose of relocating the filter and intake tract to access denser intake air under normal driving conditions, a common approach for breathing upgrades on turbocharged engines.
