TiAL Q 50mm BOV (TiAL Flange) | Boost Refrence Required



Bov’s are generally a personal preference mod. It’s about what sound you like. Performance-wise, all of the bov’s generally perform the same on the OEM Flange. If you are planning on swapping out your turbo to a larger aftermarket unit, I would upgrade to charge pipes with a TiAL flange to allow the use of bov with a larger diameter valve like the Turbosmart Raceport. 


**This BOV does require a boost reference to work. We recommend the Turbosmart Boost Reference adapter to make the installation easier. Removing the factory electronic bov will cause a P0035 check engine light to show. This will not impact how the vehicle drives or performs in any way. If you would like a BOV upgrade without a check engine light, please see the Turbosmart EM BOV that we sell**

Tial’s Q is the latest generation of TiAL blow off valve. This is the highest flowing blow-off valve on the market. It’s offered with a variety of springs for different vacuum levels and a special spring specifically for supercharged vehicles.


The Q bolts right up to any standard TiAL or similar blow off valve flange, allowing you to upgrade without having to re-weld a charge pipe. Through countless hours of R&D, TiAL was able to make the same size valve flow a staggering 60% more than the original design! This is one of the highest quality and most durable/proven VTA BOV designs.
