Note: On some models BMW has omitted the mounting hardware required to install this skidplate. For those customers you can go to any BMW dealer and order kit #71 60 8 526 643 Mounting Parts Set.
Constructed of a 4mm-thick aluminum base plate and 3mm-thick side plates for heavy-duty, light-weight protection. Where the base plates and side plates overlap, it forms a riveted 7mm-thick rail for extra rigidity. Base plate includes side protectors that wrap around the engine block to provide both bottom and side protection.
