bought them from tweakit motorsports or something like that out of australia or new zealand. lost my job and had to sell my treasures. just found these hiding in the back of the closet. they are brand new unused, made of aluminum and made to fit the 4ag fuel injector holes. they are awsome as they are removable when you need to swap back to smog or if you dont want to ruin a good head by gluing random **** into the fuel injector port.
