Manage excess boost pressure and shield your compressor turbine with this billet aluminium dual port blow off valve engineered for Mazdaspeed 3, Mazdaspeed 6, Subaru WRX, Impreza, Forester XT, and Legacy GT platforms. The reinforced dual-port architecture vents spent gases rapidly when you lift off the throttle, minimizing turbo lag between gear changes while preventing compressor surge. Machined from solid aluminium alloy, it replaces worn factory valves or makeshift bypass setups with a direct-fit unit that maintains steady airflow and supports higher horsepower tunes.

Benefits & Tips

  • Route the outlet hose toward the mass airflow sensor or a confirmed bypass line to keep your ECU readings accurate.
  • The BL-series Mazdaspeed 3 (2010–2013) requires an aftermarket airbox to function properly; verify your intake piping layout before mounting.
  • Apply a small amount of high-temperature thread sealant to fittings, avoiding the internal valve mechanism to ensure crisp operation during track or street use.
