Suplex Coil Spring. This part generally fits BMW vehicles and includes models such as X3 with the trims of 2.5i Sport Utility 4-Door,3.0i Sport Utilit y 4-Door,xDrive30i Sport Utility 4-Door. The engine types may include 2.5L 2494CC 152Cu.
Springs fit good. Only time will tell as to how long they last. I see it was a design flaw in the old one the material is too small near the ends and that's where they break.
