Add the iconic BOV sound to your Subaru with the PERRIN Diverter Valve Spacer. This simple bolt-on mod doesn't require a tune and won't trigger a check engine light.
Turbo Sounds, Unlocked
The PERRIN Diverter Valve Spacer vents unused charge air to the atmosphere between shifts, producing the iconic BOV sound. Unlike a traditional vent-to-atmosphere bypass valve, it does not trigger a CEL because the OEM diverter valve continues to operate normally.
Construction
The PERRIN Diverter Valve Spacer is CNC-machined from 6061-T6 aluminum and anodized red for corrosion resistance.
No Tuning Required
This part is designed and tested to work safely on your vehicle without any tuning required. Confirm any tune or recalibration you add is specific for all modifications on the vehicle.
