The Type 5 series is Turbosmart's most popular range. The Type 5 valve has been designed for high flow and performance. Type 5 valves are well suited for both street vehicles and race machines. Made from tough and durable billet aluminum and including many innovative features like the billet V-band clamp for fast and reliable installation. Turbosmart BOVs have big flow capabilities while being small in size and light in weight. Performance, reliability and high quality manufacturing sets Turbosmart Type 5 BOVs apart from the rest.

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!
Plumb Back - Full time recirculating. A quiet alternative to the atmospheric BOV, the Plumb Back systems vents all excess pressure back into the intake system.
