The Bilstein B8 Performance Plus 36mm monotube front left strut is a performance upgrade to OE dampers specified for certain BMW 323i/325i/328i/335i front applications and intended to be paired with lowering springs. It delivers application‑specific valve settings in a monotube design for improved handling response. Each damper is rigorously tested to meet or exceed OE standards.
