The TiAL QRJ is our latest boost control valve. Designed with the needs of high performance recirculating systems in mind. The QRJ features a new body design, compact installation envelope, high-flow capacity, and configurable inlet and outlet ports.
  • For use on turbo-charged and super-charged applications (Paxton, Vortec, etc.). The body and all internal components are CNC-machined from 6061 aluminum alloy. It features a large 1.50 in (38.5mm) valve.
  • Optional configurations of Hose and or V-band connections for the inlet and outlet ports.
  • The valve seat seal utilizes a Viton O-ring that is clamped in place to prevent the possibility of sticking to the seat and pulling out. The valve stem and guide are Teflon-lubricated, hard anodize-coated for wear resistance.
  • The QRJ comes with our own machined aluminum banjo-type air fitting and bolt, with over sized 10mm hose barb for quick actuator response.
  • Color anodized aluminum options (Silver, Red, Blue, Purple, Black).

    • What type of inlet and outlet size would I need for the piping kit for a 15 wrx

      The 15+ WRX uses a 1" outlet and a 29mm inlet. If you are going to run our piping kit and get it flanged for a TiAL BOV we recommend the V-band Q adapter.
