Product Update: New Kompact Dual Port BOVs

Turbosmart has introduced three new Kompact Dual Port BOVs. These new Kompacts offer a smaller, lower-priced alternative to the existing model-specific Type 5 BOV kits for certain Mazda, Subaru and Nissan models.

Why did we make them?

These new Kompact Dual Ports offer an alternative to the existing Kompact Plumb Backs, for owners who want the sound of a Dual Port BOV, but do not require the heavier-duty performance of the larger and higher priced Type 5 for the cars listed below.

The Kompact is suited to owners of otherwise stock or mildly modified vehicles, seeking the improved performance of an Turbosmart BOV with that classic vent-to-atmosphere sound.

The existing Kompact Plumb Back for these applications is ideal for those who prefer the quieter operation of a recirculating BOV, while the Type 5 is ideal for more modified cars running increased boost levels.

What’s great about it?

  • Billet aluminum construction and lightweight precision-machined piston for excellent sealing, response and boost holding capability.
  • Significant performance improvements compared to standard valves, which often bleed boost and crack with age and wear – especially for these older vehicles.
  • Dual Port design gives the vent-to-atmosphere ‘pssh’ that people love, while still recirculating enough air to keep the engine’s sensors happy.
  • Supplied blanking plug gives customers the option of converting the Dual Port to a full recirculating or full vent-to-atmosphere valve.
  • Eradicates compressor surge, even in stock applications.
