Re: Ebay Greddy Type S style bov
actually I had both in my hands. the greddy and ebay knock off and they are almost identical. the only major differences is the diaphram on the knock off is much thinner which may lead to a sooner failure but for $20 bucks you cant go wrong. the knockoff actually seemed to blow off better vs the greddy. had to max the spring out on the greddy for it to work right compared to the knockoff.

turning the screw makes the spring tighter and the BOV open less often. I left both my springs in and have the screw half way out and 15'k later it's damn good and so loud it hurts your ears if the hood is up.
