A Mazdaspeed3 bypass valve must be selected for its actual mounting flange, inlet/recirculation plumbing, and tune—not colour. The first-generation 2007–2009 and second-generation 2010–2013 cars are often covered by the same aftermarket listings, but a valve can still require a vehicle-specific adapter, a compatible top-mount intercooler flange, or a recirculation hose connection. A recirculating BPV returns air to the intake; a vent-to-atmosphere BOV and a dual-port valve use different plumbing and may need calibration consideration. Confirm all hardware and tuning requirements with the valve and tune supplier; no valve guarantees power or reliability.

The picks, in detail
COBB LF BPV Mazdaspeed3
COBB lists its LF BPV for Mazdaspeed3 2007–2013 and Mazdaspeed6 2006–2007. It is a low-profile bypass-valve product, so verify the current COBB fitment page and recirculation routing for the installed intercooler.
- 2007–2013 Mazdaspeed3 listing
- low-profile BPV
- vehicle-specific product
- Maker names both Mazdaspeed generations
- BPV rather than color variant
- Check tune and intercooler clearance
TurboXS MS3-RBV
TurboXS part TXSMS3-RBV is a recirculating replacement valve listed for 2007–2013 Mazdaspeed3. Its retailer description says it routes excess pressure back to the intake rather than operating as a full vent-to-atmosphere valve.
- 2007–2013 fit listing
- recirculating valve
- part TXSMS3-RBV
- Exact part number
- Recirculation role clearly stated
- Retail availability can be special order
Turbosmart Plumb Back Mazdaspeed/MPS Valve
Turbosmart lists a Plumb Back kit for Mazdaspeed/MPS 3, 6, and CX-7. This is the full-recirculation route and requires the correct Mazda/Subaru flange arrangement and return hose.
- Mazdaspeed/MPS 3 listing
- full recirculation
- vehicle-specific kit family
- Manufacturer fitting-instruction listing
- Appropriate category for recirculation plumbing
- Verify kit number and flange before purchase
Turbosmart Kompact Dual Port Mazdaspeed3
The Kompact Dual Port is listed for 2007–2013 Mazdaspeed3 and can be configured as recirculation, atmosphere venting, or 50/50 dual-port operation. The chosen setup must match the installed intake return and tune strategy.
- 2007–2013 fit listing
- recirculation or venting configurations
- dual-port valve
- Configuration choices are published
- One valve family for several plumbing approaches
- Do not change venting mode without checking tune requirements
Turbosmart Supersonic Mazdaspeed/MPS Kit
Turbosmart’s fitting-instructions catalog includes a Supersonic kit for Mazdaspeed/MPS 3, 6, and CX-7. This is a venting BOV option, not a recirculating BPV; use it only with the specified adapter and compatible calibration.
- Mazdaspeed/MPS kit
- vent-to-atmosphere configuration
- vehicle-specific fitting listing
- Clearly labelled near-match configuration
- Manufacturer kit family
- Not a direct recirculating replacement
Turbosmart Mazda/Subaru Flange Adapter TS-0205-2055
A hardware near-match rather than a valve: this $115.99 adapter is specifically listed for Mazda 3 MPS, 6 MPS, and CX-7 and accepts Turbosmart universal Plumback, Dual Port, and Supersonic valves by V-band. It includes a gasket.
- part TS-0205-2055
- Mazda 3 MPS listed
- V-band universal-valve adapter
- Exact flange solution for compatible Turbosmart valves
- Gasket included
- Adapter alone is not a bypass valve
Forge Motorsport Mazdaspeed3 BPV
Forge’s Mazdaspeed3 BPV is a recirculating aftermarket bypass-valve option commonly sold for the platform. Confirm the current part number, generation fitment, and supplied flange against the installed OEM or aftermarket top-mount intercooler.
- recirculating BPV
- Mazdaspeed3 application
- aftermarket valve
- Direct BPV category
- Established platform option
- Verify exact current kit before ordering
CorkSport Dual VTA BPV
CorkSport’s Dual VTA BPV is a Mazdaspeed platform dual-function valve that recirculates under ordinary operation and vents under higher boost according to the product description. Treat it as a plumbing and tune choice, not a sound-only accessory.
- dual recirculation/venting concept
- Mazdaspeed application
- CorkSport product
- Distinct hybrid operating concept
- Platform-focused supplier
- Venting behaviour needs tune and intake compatibility review
HKS Super SQV IV with Mazdaspeed Adapter
The HKS Super SQV IV is a valve that can be used on a Mazdaspeed3 only with the correct vehicle-specific adapter/flange and, for recirculation, the relevant return hardware. It is not a direct fit based on the HKS name alone.
- adapter-dependent installation
- HKS valve platform
- recirculation hardware needed
- Widely supported valve family
- Useful only when complete kit is verified
- Wrong Subaru or generic flange will not establish Mazdaspeed fit
Buying tips
- Identify the car as 2007–2009 or 2010–2013, then inspect the actual intercooler flange and return hose before ordering.
- A full-recirc BPV, 50/50 dual-port valve, and full atmospheric BOV are different plumbing choices. Match the selection to the intake and tune documentation.
- Pressure-test the charge system after installation and consult the tuner if boost control, AFR, or drivability changes.
