Valve cover Siebenrock
Four ribs

The classic round valve cover was the first original Siebenrock product in 1992. The improvement designed by Jochen Siebenrock at the time was so ingenious that it was later even adopted by BMW for series production. Is it even possible to optimize such an icon? Siebenrock can, and 20 years later he has provided the classic with a world first that boxer fans and customizers are already enthusiastically celebrating.
Instead of the usual two, the new Siebenrock valve cover now has four narrower ribs, creating a unique, unprecedented look for all two-valve boxers from 1969 onwards. The patented design skillfully plays with color and finish. Whether classic casting, cool matte black or both, monochromatic or with shiny polished edges, here every classic BMW gets a whole new, more delicate look.
As usual with Siebenrock, the workmanship is beyond reproach. The complete valve cover is manufactured from A-Z in southern Germany. On the coated versions, the edges are additionally hand-sealed, so that the surface permanently holds what it promises right up to the edge.
