Utilizing GFB's proven TMS (Turbo Management System) technology, this valve ensures rapid boost recovery during gear shifts, significantly improving your car's throttle response.

Key Benefits for Your Subaru:

  • TMS Technology: Minimizes boost loss and ensures your turbo stays in the optimal power band.
  • High-Pressure Ready: Capable of withstanding boost pressures exceeding 100psi, perfect for tuned engines.
  • Recirculating Design: Maintains factory-style operation while offering superior internal construction.
  • Direct Fitment: Engineered specifically for 2008+ Subaru WRX, 2003-2009 Legacy GT, and 2009-2012 Forester XT models.

Whether you are daily driving or hitting the track, the Mach 2 offers the reliability and performance gains you need. It is designed to hold more boost than any factory turbo can produce, ensuring your engine runs efficiently under all conditions.
