Original BMW M-Power Engine Oil Filler Cap for BMW E46 M3 and Z3 M Coupe and M Roadster (1998–2002)

Sealing the oil fill opening on BMW's S52 and S54 M engines, this Original BMW M-Power oil filler cap fits the 2002 E46 M3 and the 1998–2002 Z3 M Coupe and M Roadster. An oil filler cap closes the opening used to top up engine oil and keeps oil and crankcase vapor from escaping while the engine runs. BMW's parts data names this part the cap for oil filler and marks it with the M-Power designation used on its M engines. It weighs 41 g, is made in Slovakia, and is sold as a single cap. BMW shows production of this number starting in April 1996.

Original BMW Parts carry a 24-month parts warranty.

This cap is specific to BMW M engines. BMW applies 11-12-1-405-452 to the S52 3.2-liter engine and the S54 engine. One cap serves both the E46 M3 and the Z3 M cars, so a shop keeping M parts on the shelf can stock a single number for both. A worn cap typically shows itself through cracking or oil leaking around the cap.
