HKS 07-09 Mazdaspeed 3/CX-7 SSQV4 BOV Kit

Fits 2007-2009 Mazda Mazdaspeed 3 and CX-7 models. The HKS Super SQV4 (Super Sequential Blow Off Valve) kit is engineered to prevent compressor surge and maintain consistent boost response. Unlike standard push-type valves that can leak under high boost, the HKS pull-type relief design uses a differential pressure control system that remains tightly sealed during boost, only opening when triggered by pressure differentials.

The SSQV4 features a dual-stage sequential valve system and a nickel-plated, die-cast aluminum primary valve for long-term durability. This kit includes the signature HKS triple-fin design, producing the iconic high-frequency discharge sound during gear shifts and deceleration. This is a vehicle-specific application designed for a direct-fit installation on the 2.3L MZR DISI Turbo engine.

  • Direct-fit kit for 2.3L MZR DISI Turbo engines
  • Pull-type relief design ensures the valve stays shut under high boost
  • Dual-stage sequential valve structure for improved throttle response
  • High-quality aluminum die-cast body with silver finish
  • Includes all necessary hardware, hoses, and vehicle-specific mounting flange
  • Manufacturer Part Number: 71008-AZ008
