I purchased a Greddy type S Blow off Valve from JRios...all i have to say is he is a man of his word. He sent me a PM telling me the day it was sent....and about 2 days later it arrived. Blow Off Valve came in nicely wrapped. Nothing but smiles from me...he also gave me some advice on what type of currency to mail next time to Puerto Rico ;) Nice doing business with ya!
