Original BMW Cylinder Head Cover, Cylinders 1–4, for BMW M5, M6, M6 Gran Coupe, X5 M, and X6 M (2012–2016)

Covering cylinders 1–4, this Original BMW cylinder head cover is the valve cover for the S63N engine in the 2012–2016 BMW M5 and M6 and the S63R engine in the 2015 X5 M and the 2015–2016 X6 M. Made in Germany, it is sold as a single piece and weighs 4.2 kg (9.3 lb). BMW shows production of this number starting in July 2012. A valve cover seals the top of the cylinder head, holding oil in around the camshafts and keeping dirt away from the valvetrain.

Original BMW Parts carry a 24-month parts warranty.

The engine takes more than one head cover, and BMW designates this one for cylinders 1–4, shown as position 1 on BMW's valve cover diagram for these cars. It supersedes the earlier 11-12-7-843-506, so a receipt or removed cover carrying that older number points to this part.

Common Questions

Is this a new cover or a used core?
It is a brand-new, unused Original BMW part.

Will it replace the older 11-12-7-843-506 cover?
Yes. BMW marks the change as exchangeable retrospectively, so this cover goes on cars that were built with the earlier number.
