Engine cover foam.
The last time I took my plastic engine cover off to do a job the foam acoustic layer gel apart so I binned it. To be honest I didn't really notice a difference when I started it afterwards so forgot about it.
However, yesterday I went to see my dad who buys cheap bangers to flip when he comes across them. He's just bought a 2004 E60 530d with a lot of miles on it. The battery had gone flat so we jumped it with mine. As we stood there with both engines side by side running it occurred to me that his did indeed sound quieter!
So, can this foam layer be bought separately or was it fitted as a complete thing with the plastic cover as shown on real OEM.
Idle musings really, just wondered.
Thanks.
