Turbo XS 50/50 Racing Bypass Valve for Subaru WRX & STI

Enhance your Subaru's turbocharger response and reliability with the Turbo XS 50/50 Racing Bypass Valve. Engineered for the 2002-2007 Subaru Impreza WRX and the 2004-2009 Subaru Impreza WRX STI, this valve offers a unique blend of recirculating and atmospheric venting, providing both smooth idling and an audible turbo sound.

Optimized Turbo Performance

The 50/50 design allows for approximately half of the bypassed air to be recirculated back into the intake system, maintaining smooth idling and preventing check engine lights, while the other half is vented to the atmosphere, producing the characteristic turbo blow-off sound. This balance ensures optimal turbocharger performance and longevity.

  • Designed for 2002-2007 Subaru Impreza WRX and 2004-2009 Subaru Impreza WRX STI.
  • 50/50 split: Recirculates some air for smooth idle, vents some for sound.
  • Improves turbo spool and reduces compressor surge.
  • Durable construction for reliable operation under boost.
  • Direct replacement for the factory bypass valve.

This Turbo XS bypass valve is an excellent upgrade for enthusiasts looking to fine-tune their turbo system's performance and sound. Experience improved throttle response and enjoy the distinctive sound of your turbocharger. Upgrade your Subaru with quality parts from GGCRACING.
