CNracing Performance products co.,ltd offers BOV made of 6061 aluminum , CNC machined, some of them can be anodized.

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 it’s working properly.
