AVO Blow Off Valve Blue WRX (2008-2014) LGT (2005-2009) Hyundai The OS Giken STR ClutchAVO utilizes the latest technology in lightweight internal piston valving to ensure optimum blow off response at all times. The design of the V3 BOV has been updated with new internals to better manage compressor surge.
