The Mazdaspeed Vehicles use a by-pass-valve (BPV) system to recirculate excess pressure from the turbo when the throttle closes. When upgrading from the factory valve it's important to maintain this system.

  • cp-e HeliHose flexible silicone hose for perfect fitment
  • Stainless Liner clamps
  • Complete Bolt-on application and install

HKS has been one of the most recognized names in the forced induction industry, offering the legendary HKS SSQV valve, now in its 4th generation. The unique tunable sound sets this valve apart from others along with its automatic adjustment to boost pressures.


We at cp-e designed a kit for the Mazda MZR 2.3l DISI motor to specifically utilize the HKS SSQV Valve. The kit comes with everything needed for a completely bolt-on, carefree and easy installation.


We designed a low profile CNC machined adapter flange to bolt on to the factory location and interface with the HKS valve. We also included our new, specially designed HeliHose a flexible silicone hose that routes the vented air back into the inlet pipe, following the OEM design. The supplied Stainless Liner clamps ensure a tight fit without damaging the silicone.
