JBR 2010-2013 Mazdaspeed 3 TiAL Q BLow Off Valve


SKU: TIAL-BOV-3 Category:



– For use on turbo-charged and super-charged applications (Paxton, Vortec, etc.). The body and all internal components are CNC-machined from 6061 aluminum alloy. It features a large 1.98 in (50.5mm) valve.

– The V-Band design aluminum mounting clamp gives a very clean and unique appearance. The clamp uses Stainless Steel hardware for a long lasting, corrosion-free appearance.

– The valve seal utilizes a Viton O-ring that is clamped in place to prevent the possibility of sticking to the seat and pulling out. The valve stem and guide are Teflon-lubricated, hard anodize-coated for wear resistance.

– The Blow Off Valve also comes with our own machined aluminum banjo-type air fitting and bolt, with over sized 10mm hose barb for quick actuator response. The actuator has a high temp silicone Nomex-reinforced diaphragm for long life.

– 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 the highest flowing BOV on the market.
