Grimmspeed StealthBox Cold Air Intake BLACK - Subaru 15-21 WRX - 060060 919 Series ACT’s 6-pad rigid race discsInspiration for the StealthBox Intake came from internal discussions about what we wanted from an intake system for the 2015+ WRX.

We wanted an intake that purred quietly under normal driving circumstances, but would roar at wide open throttle. We wanted an intake that looked at home in the well sported 2015+ WRX engine bay instead of a shoebox
