Hi I was just wondering if anyone knew anything about this "HyperBoost" diverter valve that i found online:

It looks really great and all, but Saabs seem to be very picky about custom parts (as you all must know). Any feedback is appreciated, Thx.

It's just a flash looking recirculating dump valve.

If your original one isn't knackered then you won't notice much of a difference by fitting it.
