Fit perfect, except for the seal gel is a good idea to get a RTV gun, it’s not easy to squeeze without it.

Do yourself a favor and get a caulk gun for the sealant. Great kit, my hoses were old and hard, and my gaskets and breather covers were leaking. Hoses have shapes marked on the ends to let you know what orientation to install them. connect before you install.

Very nice and it comes with everything

I bought this for my '06 E500, but I accidentally used this kit on my '04 E55. The M113 engine is basically the same between them so the gaskets are identical and fit perfect. I did save the breathers for the correct car though. When I did work on the E500, the breathers fit absolutely perfect. The tube of chemical gasket is real nasty and forms an instant bond while sticking to everything else it bumps against. Just apply a 2mm sized bead around the inside of the top crankcase breather that attaches to the actual valve cover and use the bolts because if you try and reuse the factory aluminum bolts, they will snap off in the cover. Ask me how I know?

Fits perfectly with my 06 E500 would recommend getting your spark plugs done at the same time
