Differently colored replacement restrictors (restrictor yellow colored, diameter of bore/constriction 1.54 mm, restrictor red colored, diameter of bore/constriction 1.42 mm), therefore heed assignment (different matching of refrigerant circuit).
Refrigerant lines from evaporator to compressor/reservoir are available in different versions, depending on vehicle model.
