HKS 08-10 WRX / 05-06 Legacy 2.5 GT SSQV4 BOV Kit

$434.50

$434.50

Fits 2008-2010 Subaru WRX and 2005-2006 Subaru Legacy 2.5GT.

The HKS Super SQV4 (Super Sequential Blow Off Valve) utilizes a unique pull-type relief structure and a differential pressure control system. Unlike typical push-type blow off valves that can leak under high boost, the SSQV4 remains closed during boost because the pressure actually holds the valve against its seat. This design allows for a broad operating range, maintaining stable performance from low-vacuum environments to high-boost applications.

This vehicle-specific kit (MPN: 71008-AF012) is engineered for a direct fit, replacing the factory bypass valve with a high-quality aluminum die-cast body. The included triple-fin design produces the signature HKS high-frequency sound during discharge, providing both audible feedback and performance reliability.

  • Dual-stage sequential valve for optimal response across the RPM range
  • Pull-type valve operation eliminates boost leaks under high pressure
  • High-quality silver-coated aluminum die-cast body for durability
  • Includes vehicle-specific mounting flange, O-ring, and snap ring
  • Manufacturer Part Number: 71008-AF012
