Description

The Tial Q valve is Tial's newest blow off valve. Improving upon their old design that has been proven for over nine years to be one of the best performing valves on the market. They were able to design this valve to flow 60% more than the original design. The Q valve uses the same flange as the original version to allow for an easy upgrade.
The spring pressure in the valve does not correlate with the amount of boost pressure you want to run. The size spring you need is determined by your engine vacuum at idle. Please refer to the charge below to select the right pressure for you.

  • Q: 2014 STI  Miguelo 2 years ago

    Answer

    How do i know witch spring to use ? my sti is 14.7 psi .And how much psi it can hold? thank u


    • A: The spring you need is based on the vacuum your car pulls at idle. You will need to get a vacuum reading from an Accessport, Boost Gauge, or Factory Diagnostic Tool. After you have this measurement, refer to the provided table to see which spring would be best. This BOV does not have a specific rating for boost pressure.

  • Q: springs   rubensahagunjr90744 3 years ago

    Answer

    will this bov come with the extra springs listed above or will i have to purchase separate


    • A: Springs for the Tial Blowoff Valves must be purchased separately, this unit comes with the 11 PSI spring pre-installed.


      Nick S. 3 years ago
    • A: No, This BOV will only come with the 11 PSI spring. If a different spring is needed for your setup, you will need to purchase the correct spring separately. Spring options can be found in our Blow Off Valve Springs section.
