Ok, cannot help with instructions for it, there should be some with it. If it is for a Saab check it come wit the correct adaptor plate.

OK VTA valves on a car not set up for VTA can cause problems and a loss of performance. The valve reduces compressor surge by allowing the compressed air to vent to the atmosphere (VTA), making a distinct hissing sound, or recirculated into the intake upstream of the compressor inlet (Recirculating). the ecu monitors the pressures, etc and if there is a change it can be detrimental to performance.

Also there are a lot of fakes out there coming in from the likes of China so you need to know you are buying the real thing.

Are you just after a VTA type for the 'boy racer' noise? There is not much wrong with the OE black plastic Bosch unit, and if it fails it is easily replaced and comparitively cheap. I have also fitted a Forge recirc type to one of my cars which is obviously just as easy to fit but more expensive and adds some bling if that is what is wanted.
