Valve Cover Nut Grommet, BMW - E46 M3, MZ3 S54, Z4M (S54)

Rubber grommet seal between valve cover and cylinder head.

These seals tend to harden and shrink over time, which can cause oil leaks from the valve cover. They are easily replaced during any valve cover work.

Sold per seal. S54 engines take 13 seals.

This is a Genuine BMW valve cover seal with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
