Turbosmart TS-0205-1215 Plumb Back Blow Off Valve Blue Subaru

The Turbosmart TS-0205-1215 Plumb Back Blow Off Valve is a fully recirculating BOV engineered for Subaru turbocharged applications. Unlike atmospheric blow-off valves that vent pressurized air to the outside, the Plumb Back design redirects all excess compressor pressure back into the intake system — keeping operation completely quiet and street-legal while delivering the performance and reliability benefits of a high-quality aftermarket BOV.

Constructed from durable billet aluminum and finished in anodized blue, this valve is built to withstand the rigors of boosted performance driving. Its factory-style flange design allows for a straightforward direct bolt-on installation, and the spring preload is fully adjustable via a rotating cap — no tools required — so you can fine-tune valve response to match your specific boost and vacuum levels.

Key Features:

• Fully recirculating (plumb back) design — vents all excess boost pressure back into the intake for silent operation
• Billet aluminum construction — durable, lightweight, and corrosion resistant
• Blue anodized finish for a clean, aggressive underhood appearance
• Factory-style flange enables direct bolt-on fitment with no modifications
• Adjustable spring preload — rotating cap allows tool-free tuning from soft to firm
• Ideal for mass airflow (MAF) sensor-equipped vehicles and air-flow sensitive intake systems
• Prevents foreign matter ingestion with its fully sealed recirculating design
• Backed by Turbosmart's motorsport-proven design and testing standards

Includes: Blow off valve, gasket, and red spring rated -17 to -14 in/Hg (pre-installed).
