TiAL Sport Q BOV 10 PSI Spring - Blue - 002567

The TiAL Sport Q BOV with 10 PSI Spring in Blue (Part #002567) is a high-performance blow off valve designed for turbocharged applications where precise boost pressure management matters. The TiAL Q BOV is a widely recognized name in the forced-induction performance community, and this 10 PSI blue spring variant lets tuners dial in the valve's opening threshold to match their specific boost setup. Whether you're building a track car, a street-performance vehicle, or a dedicated time-attack machine, this BOV delivers the responsive venting and repeatability that serious turbo builds demand.

Key Features & Benefits

• 10 PSI Opening Spring: The included blue spring is rated to open at 10 PSI, allowing the valve to vent boost pressure at the right moment — helping protect your turbocharger and intercooler piping from compressor surge during throttle-off events.
• TiAL Q BOV Platform: Built on TiAL Sport's well-established Q-series blow off valve, a design trusted by enthusiasts and professional tuners for its consistent sealing, clean actuation, and durable construction.
• Color-Coded Spring Identification: The blue spring color makes it easy to identify your spring rate at a glance — useful when swapping springs or comparing setups across multiple builds.
• Multiple Spring Rates Available: TiAL offers the Q BOV with springs ranging from 8 PSI up to 12 PSI (and beyond), so you can choose the exact opening threshold that suits your boost level and tuning strategy. This 10 PSI variant is a popular middle-ground choice for moderate to aggressive street and track builds.
• Optional Flange Material Upgrades: Available flange options include Aluminum, Mild Steel, and Stainless Steel (sold separately), giving you flexibility to match your piping material and environmental requirements.
• Universal Fitment: The Q BOV is designed as a universal blow off valve, compatible with a wide range of turbocharged platforms when paired with the appropriate flange for your intercooler piping.

Fitment

The TiAL Q BOV is a universal blow off valve and is not vehicle-specific. It is designed to be welded or clamped to your intercooler piping using a compatible flange (sold separately — available in Aluminum, Mild Steel, or Stainless Steel). It is suitable for any turbocharged vehicle where your piping, boost levels, and vacuum/pressure reference can accommodate the Q BOV's installation requirements. Because fitment depends on your specific intercooler piping layout, flange selection, and tuning setup, we strongly recommend contacting our fitment team before ordering if you have any questions about compatibility with your build.

Important: This product is not legal for sale or use in California (not CARB compliant).

Frequently Asked Questions

Q: What vehicles does the TiAL Q BOV 10 PSI Blue Spring (002567) fit?
A: The TiAL Q BOV is a universal blow off valve — it is not pre-configured for any specific make or model. Fitment requires a compatible flange (sold separately) that can be welded or adapted to your intercooler piping. If you're unsure whether it will work with your setup, contact our team and we'll help you sort it out before you order.

Q: What flange do I need, and is it included?
A: The flange is not included with this listing. TiAL offers compatible flanges separately in Aluminum (#001647), Mild Steel (#001648), and Stainless Steel (#001649). The right choice depends on your piping material and installation environment.

Q: What's the difference between the 10 PSI blue spring and other TiAL Q BOV spring options?
A: The spring rate determines the boost pressure at which the valve begins to open. TiAL offers Q BOV variants with springs rated at 8 PSI, 10 PSI, 11 PSI, 12 PSI, and others. The 10 PSI blue spring is a popular choice for builds running moderate boost levels. If your tune calls for a different threshold, TiAL's color-coded spring system makes it straightforward to identify and swap springs.

Q: Can I use this BOV in California?
A: No. This product is not CARB legal and is not for sale in California. It is intended for off-road or race use in states where non-CARB emissions equipment is permitted.
