Features:

• Clever modular design - all Type 5 blow-off valves are simple to take apart and modify. Want to turn your vent-to-atmosphere blow-off valve into a plumb back valve? It can be done in a matter of minutes! Trumpets can be unscrewed and swapped for blanking plugs and hose fitting, or back the other way. Likewise inlet flanges, hose fittings and vee-band fittings, are all interchangeable.
• Precision machining and assembly - the piston and valve body are measured to mere fractions of a millimeter, and perfectly matched to fit each other exactly. Because of this precision, an o-ring is not needed to create a seal.
• A range of vehicle specific applications including WRX, STI, EVO, GT-R, MPS (MazdaSpeed3), and more.

  The Type 5 is available in three different styles:
• Supersonic - Full time vent-to-atmosphere. A full atmospheric BOV for racers and serious enthusiasts who want to be noticed. Supersonic provides a superior flow performance with the famous supersonic sound.

• Dual Port - Half vent-to-atmosphere, half recirculating, offers multiple easy to change configurations. The best of both worlds. Also, The Dual Port can be configured as a Supersonic, Megasonic, Plumb Back or Dual Port making it Turbosmart's most versatile BOV. So the Dual Port can essentially be Four BOVs in ONE!
