Under bonnet insulation

[vendetta]

Is this only available from the dealers I'm desperate

[pukar]

Its only about £35 fron dealers

[Jim320i]

Dealer only, I know meatballs82 can get it but that's through the dealer so you still have the wait... Which is usually 2-3 days... Which gives you time to remove the old glue

[vendetta]

Thanks for reminding me jim

[Grrrmachine]

There's loads of other offers out there though for various types of insulating foam, of various thicknesses and textures, with or without aluminium foil. Has anyone tried any of these?

[polsta]

this reminds me i need to get this ordered, has anyone got the part numbers ?

i seem to recall someone metnioning that you can get the new and older pre facelift style still ?

10 SOUND INSULATING FRONT TRUNK PANEL 1 51481911852 $54.88

lists the same if i do a 86 or a 91 e30 , could swear someone said on here you can still get the 2 different types

All the same afaik, there is a different style all together which isn't a sticky foam version but they are fitted to m3's and 325es's

[Grrrmachine]

Polsta, that number is showing up as the soundproofing under the back seat, not as bonnet insulation.

And Jim, I've got one of those solid insulation panels coming next week, so I'll be able to confirm whether it fits six-pot engines.

[Jim320i]

It will fit dude


They are the same between the m3 and 325 es and that's a m20.

Plus it pretty cool

[bigredbmw]

04 Sound insulation set 1 51481925437 $73.63

so whats this then ?

whats the part number and price for the 1 piece jobby ? anyone got pics ? although il prob keep oem with the 3 piece

[Grrrmachine]

Polsta, that part number is the iS-specific sound insulation, which has a different texture to the other foams (Sanchez's part number) if I remember correctly.

The solid panel that Jim and I are talking about is NLA, and you very rarely see it in the UK as it was only fitted to the M3, 325e and the diesels, and each model had its own specific panel:

[polsta]

ok, as above see thats whats i mentioned when someone said there were 2 types, the is textured (bit egg box like) i had in my is, felt a bit more durable than the other- when the smooth finish one is new, is it soft and not prone to anything easily pushing it in and leaving an imprint ?

[kieran325]

This was new 4 yrs ago -

[Jim320i]

This was new 4 yrs ago -

Bloody pictures

[polsta]

what was that like to touch ?

the one on my 325 like others before i removed it, was very brittle,falling apart and any touch left a permanent indent

this was my 318is

[Cloggy Saint]

It gets brittle with age, when new it's soft and spongy and will retain it's shape if anything is pushed into it.

[polsta]

whats the best to go for then ? the old or is version ?

[bss325i]

Use the correct one for the model of E30 you have.

Toyota brake cleaner is the most effeftive substance I have found to remove the old adhesive.

See my build thread for pics.

[Kedge]

They all deteriorate the same as each other over 15-20 years.

Buy the one specific for the 325i, I doubt BMW did that square cutout for no reason

[polsta]

ok cool il get it ordered, the paint mans cleaned/cleaning the underside of the bonnet anyway and removing the glue, didnt forget the toyota cleaner, hes going to put the new stuff on, along with new boot tool kit foam ive got
