The Perrin pulley cover for 2022–2025 Subaru WRX is a tall-style engine pulley cover in Black, intended for use without the Perrin AOS. The taller profile preserves clearance when the AOS is not installed and provides a discreet, factory-replacement appearance while tidying the front of the engine bay for a more finished look in WRX builds.
