I bought some injector of b26rx7 and told him I only need 2, but he said too damn bad, I am sending you 4 so there!! I think, a ok this guy is sending me double the parts for what I paid . Sure enough I get a priority package with 4 550cc injectors packaged up like it was going to be thrown out of an airplane. Pm'ed me a tracking number and let me know as soon as he shipped it, the same day I bought it. So thanks again bro I owe ya.
