Subaru Impreza WRX 01-07 Dump Valve Adjustable with BUNG BLUE


Dump Valve or Blow Off Valve Suitable for Subaru Impreza turbos between 2001-2007 (Distance between bolt holes 10cm) This item is supplied with the bung required to block your pipe after installing the valve to replace your factory recirculating type. And is adjustable - H for Hard and S for soft on the top of the valve refers to the tension of the spring. Fit to your car to give protection to your turbo, decrease turbo lag and make your car sound like a rally car! Also known as the compressor bypass valve. The Blow Off Valve helps protect your turbo from compressor surges. If you should suddenly release the throttle (while on boost), the BOV opens and dumps (by the dump tube) the inlet pressure.These surges occur when throttle is released while under turbo boost. With no place to go, the compressed air pushes back against the turbo, possibly damaging it. The Blow Off Valve will react quickly to this situation and release the compressed air, giving you a reassuring, distinctive sound to let you know itís working properly.
