Tial’s Q is the latest generation of TiAL Blow off valve. 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 – that means 60% more air is blown off per cycle! This is one of the highest quality and most durable/proven VTA BOV designs.
*We recommend soft spring pressures when Journal Bearing turbos are used – due to the thrust bearing configuration*
