Original BMW Valve Cover with Gasket Set for BMW 3 Series, 5 Series, X5, and Z3 (1998–2003)

Original BMW cylinder head cover 11-12-1-432-928 is the complete valve cover assembly for the M52 and M54 engines in 1998–2003 BMW 3 Series, 5 Series, X5, and Z3 models. It sits on top of the cylinder head and seals the valve train, holding engine oil in and keeping dirt out of the cams and valves. The cover arrives with its valve cover gasket set, part 11-12-9-070-990, already included, so the cover and gaskets go on together. BMW has produced this number since December 1997, and the assembly weighs 2.5 kg (5.6 lb).

BMW's name for this part is the cylinder head cover, the same component most owners call the valve cover. Engine code sorts these cars into two groups. On the E46 3 Series, the 323i, 323Ci, 328i, and 328Ci carry the M52, while the 325i, 325Ci, 325xi, 330i, 330Ci, and 330xi carry the M54. The E39 528i uses the M52, and the E39 525i and 530i use the M54. The E53 X5 3.0i runs the M54, and the Z3 appears in BMW's data with the M52 in 2.5 and 2.8 form and with the M54 in 2.5i and 3.0i form.

Common Questions

Why do these valve covers get replaced?
With age, this cover is known to crack, and a cracked cover can cause vacuum leaks and other running issues. Because this assembly includes the gasket set, the seals are renewed along with the cover.

Is the Z3 cover the same part as the E46 cover?
Yes. BMW uses this one number for the Z3 Coupe and Roadster, the E46 and E39 models, and the X5 3.0i in this fitment.

Where is this cover made?
This genuine BMW cylinder head cover is made in Germany.
