Perrin [08-14 WRX, 05-09 LGT] Red Blow Off Valve Recirculating

Fine-tune on the fly with the PERRIN Recirculating Blow Off Valve. Adjustable relief pressure and flow control let you tailor the valve to your modifications — loose for a smoother release at light loads, tightened for higher boost pressures — and it responds faster than the leaky OEM plastic unit.
