All of the front struts are physically interchangeable on the cars but that’s as far as it goes. This means that you can fit any of the struts to any of the cars. The ECS rod will not fit into a non ECS tube. If you fit a ECS strut to a non ECS car, it will stay in which ever setting it was last in. If you fit a non ECS to a ECS car, the ECS light will flash but the strut will work fine as a standard strut. There are a number of different non ECS struts so you should change them as a pair if you are thinking of changing them. I hope this helps.
