This is one new smog tube (AKA catalytic converter fresh air tube, air tube, converter check valve tube). This part replaces General Motors part number 25518946. This is a brand new part; it has never been installed on a vehicle.
Important Fitment Note: GM used 2 different versions of smog tube with 1981-1987 V6 cars. Fortunately, they look quite different from one another. Please inspect the picture closely to make sure it looks like the one you are replacing prior to ordering. We offer the other version under part number 55117.
