These used manifolds have been chemically cleaned and checked for any cracks or stress marks. Each manifold gets heat treated with a silver coating baked onto the inside and outside. This coating lowers engine compartment temperatures, prevents against rust & corrosion, and helps exhaust flow. All bolt holes get tapped and cleaned before and after heat coating.
Fits all 84-88 4 Cylinder. 87-88 4 Cyl. cars must use the 84-86 exhaust gasket.
