I have type RS blow off valves in stock. Just as good! PM me if you're interested!
This is true. You have to know exactly what you are looking for and how to spot the fakes. As long as it has GReddy on the side, and the lable of hard on soft on the purple hat, you should be good. But still...Becareful with buying name brand items on eBay. Especially blow off valves. Many are fakes and you get what you pay for.
