engine sound proofing

[pasenah]

Mines looking a bit old and patchy, and I've noticed a lot of cars don't have any at all.
Does it make a big difference in driving noise if the bonnet has no sound proofing?

It makes a neglible difference! What it does do though is protect the paintwork on the bonnet from the heat of the engine or it's supposed to!
It is no longer available from the dealers of Classic parts but you could always look out for an alternative.

Yeah I did wonder about the heat.
Thanks, I'll see what I can find to replace what's there.

The OEM pads aren't available from VW anymore. As ianaudia4 pointed out, its called sounds deadening but a secondary benefit is to protect the bonnet paintwork from heat. I had some repair work done on the bottom of my bonnet and the body shop recommended that the pads be put back, mostly to protect the paint.

If, for some reason, you are insane, and really want to restore the original factory look, it turns out the Porsche used the same material, and those are still available. You can purchase two sound proofing pads for a 928 and cut them to fit. They are expensive. Please don't ask how I know. But the underside of my bonnet does look really nice again

Pelican Parts in the States carries the OEM material - I'm sure its available elsewhere as well. Or go the sensible route and pick up some aftermarket material like what Blueshark posted and be happy.

Best,
Tom

Thanks guys. I'm not even gonna look at the Porsche ones as I suspect they are expensive lol, but I'll probably go with the cut to fit universal ones.
