WRX/STI Racing Bypass Valve | 02-07.

MIA's Description

The TurboXS Recirculating Bypass Valve (WS-RBV) is designed for 2002-2007 Subaru WRX and 2004-2007 Subaru Impreza STI models. This racing bypass valve, Type H34, vents excess pressure back into the car's air intake, making it ideal for Mass Air Flow (MAF) metered cars. This prevents a "rich" air/fuel ratio that can occur when venting to atmosphere. It is CNC machined from billet aluminum and brass. The valve operation is quieter compared to blow-off valves that vent to the atmosphere. It comes standard with a 34mm OD anodized aluminum hose adapter for the inlet.
