Original BMW Valve Cover Trim Cap for BMW M3 E36 and Z3 M Coupe and M Roadster (1995–2000)

The Original BMW valve cover trim cap is a small finishing cap for the top of the S50 and S52 inline-six engines in the E36 BMW M3 and the Z3 M Coupe and M Roadster. BMW's parts data calls it simply a cap. It weighs only 5 g (0.18 oz), so it is a light trim piece and not a load-bearing part. Production of this number began in March 1994. That date covers the 1995 US-market M3 and every later car in this fitment. Each cap is made in Germany and is sold individually as a single piece.

Original BMW Parts carry a 24-month parts warranty.

Engine trim caps close off the visible openings on a cover so the top of the engine looks finished. BMW applies this one part number to the 3.0 liter S50, the 3.2 liter S52 in the M3, and the S52-powered Z3 M3.2. One cap therefore serves the whole group, and you do not need to choose an engine-specific version. BMW also applies it to the E36 M3 convertible as well as the coupe and sedan, so body style does not change the part. A single new piece gives the engine a finished factory look.
