Original BMW Gasket Ring A8x13x1 for BMW E46 M3, Z3 M, and Z4 M with S54 Engine (2001–2008)

For the S54 inline six, BMW part 07-11-9-903-546 is an Original BMW gasket ring sized A8x13x1-AL, fitted to the E46 M3, Z3 M Coupe and Roadster, and Z4 M Coupe and Roadster from 2001 to 2008. BMW's size code reads as an 8 mm inner diameter, a 13 mm outer diameter, and a 1 mm thickness. Each ring weighs 1 gram (0.04 oz), and BMW shows production starting in July 2000 with no end date. It is made in Germany and sold individually. Flat gasket rings sit under a bolt or plug head and crush slightly when tightened to seal the joint.

Original BMW Parts carry a 24-month parts warranty.

Within BMW's car range this ring is specific to the S54 engine. BMW's parts data shows it on the E46 M3 coupe and cabrio, the E46 M3 CSL, the Z3 M3.2, and the E85 and E86 Z4 M3.2. That makes it an M-only part, so a standard E46 or Z4 should not be matched to it by chassis alone. The same number also appears on several BMW motorcycles.

Common Questions

Will this fit a non-M E46 or Z4?
BMW ties it to the S54 engine only, so it is not shown for standard E46 or Z4 models.

Does the M3 CSL use it?
Yes. BMW includes the E46 M3 CSL with the S54.

A small ring, but the right one keeps an S54 joint sealed.
