Features, Description, Q&A
Performance Recirculation Blow Off Valve. The Perrin Performance Black Blow Off Valve is designed to improve turbocharged vehicle performance by efficiently relieving boost pressure. It recirculates air back into the intake system, maintaining proper air-fuel ratios and throttle response during gear shifts or throttle lift. This prevents compressor surge and damage, ensuring smoother turbo operation and enhanced drivability.
Construction and Appearance. Precision CNC machined from billet 6061 aluminum, the body, piston, cap, and flange feature durable anodized finishes—red for the body, clear for the piston, and black for the cap—providing corrosion resistance and a professional look. The internal stainless steel spring ensures consistent and reliable performance.
Installation. Installation is straightforward with a direct bolt-on design requiring no modifications or drilling. The unit comes pre-set for optimal function but allows adjustable relief pressure and flow control for fine-tuning without complicated adjustments.
Warranty. This blow off valve includes a five-year warranty against defects in materials and workmanship when installed and used properly.
Application. Fits 2002-2007 Subaru WRX and 2004-2015 Subaru STI models.
