This is the best Diverter Valve I have ever bought. It tends to release pressure in the most amazing way between shifts. The blowing sound is the best blowing sound that I have ever heard this is the apple to the eye of my BOV. As far as from ordering it from Urotuning, their service is always amazing and their delivery with their carriers is on point, look elsewhere and you will not receive better service as far as European parts stores go. I totally recommend buying this gem from Urotuning if you need to replace your Diverter Valve as you won't regret the Woosh sound that it will make once you pair it with your BOV which is also sold here!!
