The Tial Sport 50mm Q-BOV features CNC-machined body and componentry from 6061 aluminum alloy. It utilises a large 1.98 in (50.5mm) valve and re-designed body to provide a huge 60% increase in flow rate over their old design! The new Q uses the same V-Band design mounting as the old BOV so they are completely interchangable. Upgrade yours now! Various colours available – please specify when ordering.
